Bonkers Bounce House [Kit]
From the Super Mario Wiki
Bonkers Bounce House [Kit] is an official course in Course World in Super Mario Maker 2. It is a level published by NintendoNM, and was created by Kit of Nintendo Minute. It is set in the underground theme and in the Super Mario World style.
The level begins with a gradual slope with a Koopa Paratroopa and a ? Block containing a Super Mushroom. After bouncing on a few horizontal and vertical Trampolines, Mario must head down a slope, then go up another slope while avoiding another Koopa Paratroopa. Mario must then head through some narrow passageways to a Warp Pipe spawning Trampolines, one of which Mario must grab to place on a higher ledge and bounce to a slope leading to the Checkpoint Flag. After avoiding three Chain Chomps, Mario must then climb a staircase with horizontal Trampolines and more Koopa Paratroopas, followed by a drop with some Spike Traps. A few more Koopa Paratroopas follow before the Giant Gate.
