I hit the right crab doing this one.

The trick is to release right while approaching the ceiling, like in this video: https://videos.maprando.com/video/5314. Added a note now to explain this.

"The turnaround method has about a 9-frame window for the turnaround.",

"and about a 7-frame window for the unmorph.",
"The after-transition ceiling mockball has an 8-frame for the morph.",
"Kagoing the crab is also possible, but it seems more difficult than all three other options, and it takes damage, so is probably pointless."

For Metal Pirates its canTrickyDashJump on top of the momentumeConservingTurnaround. If you aren't on the correct tile window it becomes a much harder jump.
I don't have a blue door patch for big boy room but it might get a pass for not being heated.

Cool, added "canTrickyDashJump" requirement to the "canMomentumConservingTurnaround" case.

If it helps, I shared a blue doors patch in #development (Map Rando discord).
