Climb to the top left of the room using the door frame, a wall jump, or jump out of the water into an IBJ. Roll through the tunnel and spin jump off the crumble block then wall jump and morph. Alternatively, it is possible to avoid falling to the crumble block with a well timed bomb boost or use Spring Ball. It is also possible to use the blue suit to break the bomb block then lose the suit and continue normally.
