Tricky Trap Pyramid [Chris]
From the Super Mario Wiki
Tricky Trap Pyramid [Chris] is an official course in Course World in Super Mario Maker 2. It is a level published by NintendoNM, and was created by Chris of the Nintendo Power podcast and shown on an episode of Nintendo Minute. It is set in the desert theme and in the Super Mario Bros. style.
The level begins with a Warp Pipe spawning Dry Bones Shells, of which Mario must enter one to ground pound an ON/OFF Switch and thus enter a Warp Door. After crouching to avoid a Thwomp, Mario must jump out of the Dry Bones Shell to reach a Seesaw. After getting a new Dry Bones Shell, Mario must the Seesaw's weight to his advantage to ground pound one side, causing a Dry Bones to reach a high-up platform and bounce on a Note Block to release a Vine, allowing Mario to head up and reach a Checkpoint Flag and another Warp Pipe. After crouching to avoid some Big Thwomps and climb on another Vine, Mario must bounce on some Parabones to reach another Warp Pipe. Mario must then avoid parachuting Fish Bones to enter a Warp Pipe on the left, where he will find another Checkpoint Flag, and must jump in and out of a parachuting Dry Bones Shell twice to safely grab a Key and place it into a Key Door in the area with Fish Bones. Afterwards, Mario must kick a Dry Bones Shell into a Big Dry Bones to enter yet another Key Door and a subsequent Warp Pipe, which leads to a slope descending to the Goal Pole.
"In a shell, Down = hide, jump + Down = stomp, shoulder buttons = jump out."
