Be sure not to lure the first crab on the right wall until the slow global crab is near. Freeze the crab coming down as a platform to stand on to jump onto the frozen global crab on the right. Near the end, use the global crab to get onto the top left corner of the room, then jump towards the walkway leading to the door.
