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.

Entrance condition:

{
  "comeInJumping": {
    "speedBooster": true,
    "minTiles": 12.4375
  }
}

Requires:

{
  "notable": "Cross Room Jump with Screw Attack"
}
"canInsaneJump"
"canCrossRoomJumpIntoWater"
"ScrewAttack"
"canMomentumConservingTurnaround"

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.
