Trap Floor

Trap Floor is a minigame in Mario Party Advance. Its name is a pun on "trapdoor".

Gameplay
The goal of the game is to open trap doors, dropping the Koopa Kids to the floor below and eventually into the pits below the doors, and keeping them away from you. If they fall through a trapdoor without opening the one below, it will fall and bounce onto the ground beside it, dazed.
