Jump and mid-air morph off a crumble block to begin the IBJ. Use double bomb jumps to make it up quickly before the shot block respawns.

Requires:

{
  "obstaclesCleared": [
    "A"
  ]
}
"canCrumbleJump"
"canInsaneJump"
"canJumpIntoIBJ"
"canDoubleBombJump"
{
  "heatFrames": 360
}

Dev note: This is likely to only be useful if the in-room item is Bombs, and Samus had to break the blocks with a Power Bomb to get to it.
