Carry Temporary Blue through the top door to break the left side of the bomb blocks. Morph while falling through the shot block to bounce on the crumble blocks towards the morph tunnel. Then unmorph near the wall to fall straight down with temporary blue, if needed.

Entrance condition:

{
  "comeInWithTemporaryBlue": {}
}

Requires:

{
  "obstaclesNotCleared": [
    "A"
  ]
}
"canPrepareForNextRoom"
"canChainTemporaryBlue"
"h_canUseSpringBall"
{
  "heatFrames": 300
}

Clears obstacles: B

Dev note: You could jump into the room for the initial Temporary Blue and turn around with XRay twice, but this room is heated so that would be costly.
