Mushroom is a splicable solid trampoline foreground block.
Jumping on a Mushroom will cause the player to bounce, and by holding the jump button, the player can jump higher. If the player has the High Jump mod, the player will jump even higher.
- From 2013-2014, touching the bottom of a Mushroom (and other trampoline blocks) would make the player bounce down. This, however, was later changed.
