Quickly shoot to break the shot block and then do a momentumConservingTurnaround to ascend into the little region. Another movement item will be needed to get closer to the crumble blocks.

Entrance condition:

{
  "comeInJumping": {
    "speedBooster": false,
    "minTiles": 2
  }
}

Requires:

"canTrickyJump"
"canCrossRoomJumpIntoWater"
"canMomentumConservingTurnaround"
{
  "or": [
    "canUseFrozenEnemies",
    "canSpringBallJumpMidAir",
    "HiJump"
  ]
}

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.
