Rhythm of the Koopa Shell
From the Super Mario Wiki, the Mario encyclopedia
Rhythm of the Koopa Shell is an official course in Course World in Super Mario Maker 2. It is the seventh level published by NintendoAU, with the "standard" and "puzzle-solving" tags. It is set in the sky theme for the main area and the airship theme for the sub area, in the Super Mario World style.
At the beginning of the level is a green pipe below Mario which green Koopa Troopas come out of. Mario must kick a shell onto the Note Block, causing it to continuously hit an ON/OFF Switch. Mario must make it across a section with Dotted-Line Blocks as the ON/OFF Switch is hit, timing his jumps between the red and blue blocks. Next is another green pipe giving out more green Koopa Troopas. Mario must pick up a shell and ride the Flimsy Lift along the Track, kicking the shell upward at the horizontal Trampoline, causing it to start hitting another ON/OFF Switch. Mario must ride the Flimsy Lift, avoiding an Icicle along the way. After this are two green Cheep Cheeps with one flying green Cheep Cheep. There are then two sets of three ? Blocks, with a Hidden Block between them. Right after is the green pipe which takes Mario to the sub area.
At the start of the sub area is the Checkpoint Flag. There is a Thwomp to the left activating ON/OFF Switches. After this Mario must avoid more Thwomps, several Burners, and five Skewers. Mario must then make it across ON/OFF Conveyor Belts, avoiding even more Thwomps.
