Requires a runway of at least 6 tiles (with no open end) in the adjacent room. Use a Cross Room Jump into Water followed by a delayed Momentum Conserving Turnaround. Then morph and move right to go through the Morph tunnel above, avoiding damage from the crab. With the minimal runway length, this requires precise timing.

Entrance condition:

Dev note: This strat is included for completeness, but it is technically redundant with the airball strat, which may generally be preferable due to not risking a crab hit.

Requires a runway of at least 4 tiles (with no open end) in the adjacent room. Use a Cross Room Jump into Water followed by a delayed Momentum Conserving Turnaround. Then morph and move right to go through the Morph tunnel above, avoiding damage from the crab.

Entrance condition:

"canMomentumConservingTurnaround"

Only requires a runway of 6 tiles (with no open end) in the adjacent room. Perform an air ball while against the ceiling to make it up and through the morph tunnel. If the runway length is minimal, the aim-down input must be delayed a bit (rather than buffered through the transition), so that Samus moves at a slightly higher horizontal speed for longer.

"canMomentumConservingMorph"

Requires a runway of at least 4 tiles (with no open end) in the adjacent room. Use a Cross Room Jump into Water followed by a delayed Momentum Conserving Turnaround to reach the Morph tunnel above. Climbing the Left side of the center hole will run into an unavoidable Sciser that can be passed through by Morphing. Crossing to the right from the left door requires slightly more runway and takes a more precise turnaround. Samus must also stay near a side of the center hole to reach the Morph tunnels.

Requires a runway of at least 3 tiles (with an open end) in the adjacent room. Use a Cross Room Jump into Water followed by a delayed Momentum Conserving Turnaround to reach the Morph tunnel above. Climbing the Left side of the center hole will run into an unavoidable Scisor that can be passed through by Morphing. Crossing to the right from the left door requires slightly more runway and takes a more precise turnaround. Samus must also stay near a side of the center hole to reach the Morph tunnels.

In the other room, use 6 runway tiles to gain an extra run speed of exactly $1.D, with Speed Booster unequipped. Jump into a lateral mid-air morph and touch the door transition while descending close to the ground. Hold jump to do an uncontrolled bounce immediately after the transition. Pause as Samus passes under the first ceiling Grapple block. Equip Speed Booster and unequip Spring Ball, to get a spring fling. Pause again and re-equip Spring Ball to get a second spring fling. Continue holding jump to bounce on both Grapple platforms with uncontrolled bounces; Samus must bounce on the left edge of the first platform in order to just barely make the bounce on the right edge of the second platform. Perform one more spring fling, by unequipping Spring Ball as Samus begins to descend. Samus should make it into the nook below the right door; A Flatley jump into mid-air spring ball jump will get Samus up to the door.

Dev note: A comeInSpinning entrance condition is used to ensure it is possible to enter in the right position, even though technically Samus should enter morphed rather than spinning. With longer runway, a number of variations of this strat are possible: entering with a mockball (or controlled bounce) with speed at least $4.4, it is possible to bounce immediately on entry and do two spring flings to reach the second Grapple platform directly. with the same type of entry and speeds at least $5.4, it is possible do controlled bounces on both Grapple platforms, with no spring fling needed. FIXME: stopping at node 9 (below the top door) is also possible.

Run and jump up through the door using SpeedBooster in the room below. Bonk the door frame as you pass through the transition, to cancel your horizontal momentum. You need a vertical speed of exactly 7.8800 when passing through the transition, which requires the jump to be frame perfect. After the transition, as you reach the wall, begin holding right. Begin holding angle up at any time before approaching the door (and you can continue holding it until the end of the strat). As you approach the door (an 8-frame window), while holding angle up, release right for exactly one frame. This will put Samus into a pose aiming diagonally up and to the right. Immediately fire a shot to open the door (within the same 8-frame window); if successful, you will just barely clear the grapple block and pass through the door. Several things can cause you to bonk the grapple block: 1) entering the room with too much vertical speed, 2) not pressing against the wall as you come up, 3) releasing right for more than one frame, 4) releasing right too early. As an alternative to releasing right for one frame, you can instead press shot for one frame: if successful, Samus' pose will change to aiming diagonally without a shot being fired; if shot is pressed for more than one frame, then a shot will be fired horizontally, and the cooldown will prevent you from firing diagonally in time.

"SpeedBooster"

Dev note: This strat is applicable in Crocomire's Room and the Post Crocomire Jump Room. Sufficient vertical speed could be obtained with fewer tiles, but it would require jumping further to the right (i.e., increasing minRightPosition) which would not work in PCJR unless the PB blocks are broken.

In the previous room, gain max run speed without Speed Booster equipped, requiring about 7 tiles of runway (obtaining an extra run speed of $2.0). After the transition, jump to slightly less than full height, performing a lateral mid-air morph just early enough to avoid bonking the ceiling Grapple block. Pause to equip Speed Booster before bouncing on the first Grapple platform; this provides a boost in the bounce height to be able to make it to the Grapple platform below the top door.

In the previous room, gain max run speed without Speed Booster equipped, requiring about 7 tiles of runway (obtaining an extra run speed of $2.0). Enter the room either in a mockball (or process of mockballing), or descending from a controlled Spring Ball bounce. Just after the transition, jump or bounce to slightly less than full height. Pause to equip Speed Booster before bouncing on the first Grapple platform; this provides a boost in the bounce height to be able to make it to the Grapple platform below the top door.

Come in with high speed and jump after the transition to cross the room. Precise timing is needed to jump to the correct height: too high and Samus will bonk the Grapple block, too low and Samus will not make it onto the ledge. A Powamp may be in the path of the jump but can be destroyed with blue speed.

With Speed Booster equipped, run into the room using at least about 2 tiles of runway (at least $0.C extra run speed). If needed, perform two spring flings by pausing and unequipping Spring Ball, then pausing again and re-equipping it before bouncing on the first Grapple platform. Afterward, perform additional spring flings as needed to make it across the room, taking care to avoid the Powamp.

Enter the room morphed, either in a mockball on the ground or descending from a controlled bounce, with about 1 tile worth of speed (at least $0.9 extra run speed). Use Spring Ball to jump or do a controlled bounce after the transition. While descending and before bouncing on the first Grapple platform, perform two spring flings by pausing and unequipping Spring Ball, then pausing again and re-equipping it. Afterward, perform additional spring flings as needed to make it across the room, taking care to avoid the Powamp. Note that Samus must be fully morphed when entering the room (not in the middle of a morphing animation), or the spring flings will not work, assuming Speed Booster is not equipped.

Use Spring Ball to jump or do a controlled bounce after the transition. Bounce on the first Grapple platform. Then perform a 'spring fling' by unequipping Spring Ball while descending, to reset Samus' vertical speed and be able to make it across room. Note that Samus must be fully morphed when entering the room (not in the middle of a morphing animation), or the spring fling will not work, assuming Speed Booster is not equipped.

Dev note: This strat is applicable in Crocomire's Room and the Post Crocomire Jump Room. Sufficient vertical speed could be obtained with fewer tiles, but it would require jumping further to the right (i.e., increasing minRightPosition) which would not work in PCJR unless the PB blocks are broken; since there doesn't yet appear to be any application, we don't add a separate case for that.

Needs near max horizontal speed coming from about 40 runway tiles in the adjacent room. Jump after the transition. Running a longer on the short runway is more difficult at maximum speed, but will increase the success of the jump.

  }
}

Requires:

"canCrossRoomJumpIntoWater"

Dev note: We don't require 'canTrickyDashJump' here, since any speed of at least $2.0 works; a different jump timing is needed for run speed between $2.0 and $2.3 compared to higher speeds, but there is a very large window in both cases, making it not difficult for the player to find a timing that works.

Requires running a precise distance of 7 tiles with no open end in the adjacent room, to hit a peak of the speed vs height graph (at extra run speed $2.0 or $2.1). This needs a last-frame Space Jump in the previous room. At the lower of the two possible speeds ($2.0), the jump must be done very low through the door; at the higher speed ($2.1) there is a relatively large window of vertical positions that work.

Use a platform below the door in the other room to jump through the door while aiming down, carrying upward momentum into this room. Hold down and back through the transition, to perform a momentum-conserving turnaround past the corner.

Use a platform below the door in the other room to jump through the door while aiming down, carrying upward momentum into this room. Hold down and back through the transition, to perform a momentum-conserving turnaround past the corner. Perform a mid-air Spring Ball jump, timing a pause to hit soon after the mid-air jump. Unequip Spring Ball, lay a Bomb about half a tile below the peak of the jump. Press pause at the peak of the jump, tp reequip Spring Ball immediately after Samus is boosted by the bomb. Buffer a jump out of the unpause, to get a second Spring Ball jump and make it up.

Jump through the door in the previous room, and perform an air ball soon after entering. With a last-frame jump through the door, there is a wide timing window to do the air ball. With an earlier jump through the door, the airball must be done more precisely: in this case buffer aim-down through the transition and morph immediately on entry, in order to conserve momentum while contacting the overhang.

Clears obstacles: door_1

Dev note: There is a 4-frame window for the jump that can work; jumping in the later part of that window is better as it gives a bigger window for the morph. In water physics, an airball has higher base speed ($1.8) than spin jump ($1.6) or aim down ($1.4), which is the other reason why doing it early helps, in addition to how it helps clear the overhang. Doing a ceiling mockball at the top of the room can also work, but it is more difficult, and the frame-perfect jump is required in that case.

With a 1-tile runway in the other room, this has a 2-frame window to jump before the transition.

Do a low spin jump and press against the right side of the door frame. Wall jump as low as possible, jumping as soon as possible after moving away from the wall. Immediately turn back to the right and try to press against the door frame again before the transition, while maintaining spin.

Dev note: This strat is for cases where the door frame below has only a two-tile-high surface available for wall-jumping. If a third tile is available, the jump can be done more easily.

Gain run speed to the right and jump through the door without bonking the door frame. After the transition, continue holding right while remaining in spin jump. This strat could also be performed without passing through the Toilet, but a precise down-grab would be needed to get onto the ledge at the end; in this case it would be easier to perform a standing jump instead.

Using SpeedBooster in the room below, run and jump, pressing against the right side of the door frame through the transition without breaking spin. It may be necessary to use less runway than is available, to avoid getting too much vertical speed.

Dev note: This strat is applicable in Crocomire's Room and the Post Crocomire Jump Room. Sufficient vertical speed could be obtained with fewer tiles, but it would require jumping further to the right (i.e., increasing minRightPosition) which would not work in PCJR unless the PB blocks are broken; since there doesn't yet appear to be any application, we don't add a separate case for that.

Using SpeedBooster in the room below, run and jump through the door without bonking the door frame or breaking spin. Perform a mid-air wiggle to make into onto either ledge.

Dev note: The transition likely connects to Pants Room making this strat not likely to be useful. This can be done with a slightly shorter, closed end runway.

Perform a 1-tap to gain blue speed with a significant amount of momentum. Run through the door, and jump near the end of the platform, crossing the room. If Samus gains enough height from the jump, it is possible unmorph mid-air to discard horizontal speed at the right side of the room, then pause to remorph (`canPauseRemorphTemporaryBlue`). Otherwise, a precisely timed unmorph is needed to avoid bonking the door and losing the blue state; at certain speeds, it may be necessary to briefly release jump in order to control the height for the unmorph.

Stand at an effective distance of between about 20 and 21 tiles from the door. Run through the door, and jump any time after the transition, holding jump through the entire room to make it to the other side. Samus will go over the Evirs, so there is no need for blue speed.

Requires a runway of 7 tiles (with no open end) in the adjacent room. Requires two precise inputs of jumping through the doorway and a short aiming down press before hitting the ceiling. Damage boost off of the right Evir in order to land on the first pillar. With Ice, instead freeze the Evir to land on it and avoid the damage. When entering the room with a bad jump, it is possible to perform a midair wiggle to get back to the door platform.

Gain momentum in the room to the left, then jump at the edge of the runway in this room in order to jump off of the sand and land on the first pillar. Requires a runway of 7 tiles (with no open end) in the adjacent room, and killing the second Evir with a quick super or two plasma hits (note that the particle despawns as the Evir dies).

Perform a 1-tap to gain blue speed with a significant amount of momentum. Run through the door, and jump into an airball any time after the transition, crossing the room. At higher speeds, it may be necessary to unmorph at the left side of the room while still high in the air, to discard horizontal speed, then pause to remorph (`canPauseRemorphTemporaryBlue`).

{"types":["ammo"],"requires":[]}

Dev note: This needs an extra run speed of at least $4.4. For speed $4.5, it helps to jump early and hold an aim-down pose. Speed $4.6 doesn't seem possible, as you end up too high to land without bonking the door, and too low to have time for a pause remorph? For speeds between $4.7 and $4.9, a pause remorph works. Speed $4.A is difficult but can be done with a last-frame jump, a momentum-conserving morph (ceiling mockball) while touching the second overhang, and a pause remorph. Speed $4.B doesn't seem to work as you can't avoid bonking the first overhang?

Stand at an effective distance of about 20 tiles from the door. Run through the door, and jump any time after the transition, holding jump through the entire room to make it to the other side. Samus will go over the Evirs, so there is no need for blue speed.

Dev note: This needs an extra run speed of at least $4.4, and ideally not much more than that. A little higher run speed can also work but may require releasing jump near the peak to avoid getting caught on the overhang.

Enter with enough run speed to jump (after the transition) across the full room using one Spring Ball Jump. When exiting the first Sandfall, Samus will be rising still. That is the time to Spring Ball jump. Alternatively, an immediate pause can be used to Spring Ball jump during the first narrow gap between Sandfalls. Sometimes Samus will land above the sand on the far left end of the room, where it will be necessary to unmorph and jump out.

Dev note: It is assumed that getting to the third pillar is free relative to getting to the left door.

Gain momentum in the room to the right, then jump immediately on entry in order to land on the first pillar. Jumping too late will likely put Samus into the pit. Requires a small runway of only one tile or less in the adjacent room. Jumping before the door transition will set Samus straight into an Evir projectile, knocking her into the sand.

The only current strat that would put this into logic is using a frozen Evir, so canTrickyUseFrozenEnemies is added for clarity.

Use Screw Attack to break the bomb block by entering from a non-water room with a spin jump.

Use a 2-tap shortcharge and jump into the room with a last-frame jump, breaking the bomb block with blue speed, and making it all the way through the top door. Use angle to break spin, and do a momentum conserving turnaround either on the same frame or one frame later; this first turnaround should be done early enough that the turnaround is complete by the time Samus clears the two-tile passage in the middle of the room. Do a second momentum conserving turnaround must be done somewhat late, and by switching from holding left to holding right one frame later (a perfect 'boomerang'). Shoot open the door, and use a third momentum conserving turnaround on it as it opens.

Lower run speeds are generally better, as long as the extra run speed is at least $3.4. this gives up to a 7-frame window for the first turnaround, and typically a 4-frame window for the second turnaround if the first turnaround is done early enough. A perfect boomerang is always required for the second turnaround, regardless of where in the window it is done. It is recommended to buffer the spin break, by holding angle (up or down), jump, and forward through the transition, then switching from forward to backward, with at most 1 frame of neutral in between, while still holding jump and angle.

Use Screw Attack to break the bomb block by entering from a non-water room with a spin jump, and make it all the way through the top door. Ideally, gain speed using between 13 and 13.5 tiles of runway (with an open end). Longer runway lengths can also work, up to 17 tiles, but will make the trick somewhat more precise. Use angle to break spin, and do a momentum conserving turnaround either on the same frame or one frame later; this first turnaround should be done early enough that the turnaround is complete by the time Samus clears the two-tile passage in the middle of the room. Do a second momentum conserving turnaround must be done somewhat late, and by switching from holding left to holding right one frame later (a perfect 'boomerang'). Shoot open the door, and use a third momentum conserving turnaround on it as it opens.

The optimal amount of extra run speed is $3.4 or $3.5, by using 13 tiles of runway or about a half tile more; this gives a 7-frame window for the first turnaround, and typically a 4-frame window for the second turnaround if the first turnaround is done early enough. Extra run speeds between $3.6 and $3.F can also work, but with shorter windows. A perfect boomerang is always required for the second turnaround, regardless of where in the window it is done. It is recommended to buffer the spin break, by holding angle (up or down), jump, and forward through the transition, then switching from forward to backward, with at most 1 frame of neutral in between, while still holding jump and angle.

Use Screw Attack to break the bomb block by entering from a non-water room with a spin jump, and make it all the way through the top door. Ideally, gain speed using between 13 and 13.5 tiles of runway (with an open end). Longer runway lengths can also work, up to 17 tiles, but will make the trick somewhat more precise. Use angle to break spin, and do a momentum conserving turnaround either on the same frame or one frame later; this first turnaround should be done early enough that the turnaround is complete by the time Samus clears the two-tile passage in the middle of the room. The second momentum conserving turnaround must be done somewhat late, and by switching from holding forward to holding backward one frame later (a perfect 'boomerang'). Shoot open the door, and use a third momentum conserving turnaround on it as it opens.

The optimal amount of extra run speed is $3.4 or $3.5, by using 13 tiles of runway or about a half tile more; this gives a 7-frame window for the first turnaround, and typically a 4-frame window for the second turnaround if the first turnaround is done early enough. Extra run speeds between $3.6 and $3.F can also work, but with shorter windows. A perfect boomerang is always required for the second turnaround, regardless of where in the window it is done. It is recommended to buffer the spin break, by holding angle (up or down), jump, and forward through the transition, then switching from forward to backward, with at most 1 frame of neutral in between, while still holding jump and angle.

Dev note: This does not have collision oscillation.

Use Screw Attack to break the bomb block by entering from a non-water room with a spin jump, and make it to the top. It helps to enter as low as possible and with as much horizontal speed as possible and with HiJump turned off.

Dev note: This does not have collision oscillation FIXME: It is possible to use a flash suit to get from 4 through the top door, but either requires a diagonal spark, or using this strat to get onto the top platform, which is more than this strat expects.

Gain momentum in the room to the left, then jump in this room in order to land on the first pillar. Ensure that Speed Booster is disabled. Requires a runway of only approximately 0.5 tiles in the adjacent room. Perform an air ball before hitting the ceiling in order to land on the first pillar.

Entrance condition:

Bomb boost through the doorway. Get the bomb boost while as close to the door transition as possible in order to get to the first pillar.

Entrance condition:

{
  "comeInWithBombBoost": {}

Requires:

"canCrossRoomJumpIntoWater"

Gain momentum in the room to the left, then jump at the edge of the runway in order to land on the first pillar. Requires a runway of at least 2 tiles (with no open end) in the adjacent room. Shrinking Samus' hitbox before landing makes the jump a little easier.

Entrance condition:

{
  "comeInRunning": {
    "speedBooster": "any",
    "minTiles": 1.4375

Requires:

"HiJump"
"canCrossRoomJumpIntoWater"
"canTrickyJump"
"canPlayInSand"

Dev note: This is not technically a canCrossRoomJumpIntoWater, but it is used here because of the way the momentum changes as Samus enters the water.

Gain momentum in the room to the left, then jump after entering this room in order to land on the first pillar. Ensure that Speed Booster is disabled.

Enter with at least 1 tile of run speed from an air room, with Speedbooster unequipped. Jump from near the end of the runway (though a jump from 1-2 tiles away from the end can still work). Press pause while crossing the narrow first sandfall, then perform a lateral mid-air morph after exiting the sandfall. Equip both Spring Ball and Speed Booster, and perform a mid-air Spring Ball jump at somewhere close to the maximum height. Unequip Spring Ball while descending through the wide second sidefall.

Gain momentum in the room to the left, then jump in this room in order to land on the first pillar. Ensure that Speed Booster is disabled. With a short runway of 4 tiles (with an open end) in the adjacent room, it is required to jump as late as possible at the edge of the runway in this room. Shrinking Samus' hitbox before landing makes the jump a little easier.
