Mushroom Trampolines are neon carrot round-cornered square gelatin trampolines with Macaroni and Cheese colored spots located in Big Bounce Byway. They give players the ability to jump higher on un-reachable parts of the level while bouncing on these trampolines. Bigger ones and special moving pieces also appear to exist throughout the level such as elevating up and down.
