Cutscene Ceiling Clip

Cutscene Ceiling Clips or Cutscene Clips exploit a specific kind of cutscenes to put Crash in ceilings. It only works with cutscenes that lock Crash without moving or teleporting him. The locking process tries to teleport Crash to the ground where he is but if he's just under the ceiling it will teleport him in it. Being in a jumping state or bodyslaming state might be needed.

Classroom Chaos
You can clip at the beginning of each hall monitor section, but it barely saves time.

Cavern Catastrophe
A cutscene clip is possible at the end of Cavern Catastrophe, but it's 3 seconds slower than the T-pose strat.
