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.
