Enter the room with a very specific run speed to jump from the door, and land a speedball perfectly in the tunnel to break the Bomb block.

Entrance condition:

{
  "comeInGettingBlueSpeed": {
    "length": 1,
    "openEnd": 0,
    "minExtraRunSpeed": "$5.2",
    "maxExtraRunSpeed": "$5.F"
  }
}

Requires:

{
  "notable": "Morph Tunnel SpeedBall"
}
"canInsaneJump"
"canSpeedball"
"canTrickyDashJump"
"canSlowShortCharge"

Dev note: There is 1 unusable tile in this runway. Speeds between $6.2 and $6.A can also work but are more difficult.
