Whack-a-Plant

Whack-a-Plant is a single-player minigame in Mario Party.

Gameplay
All the player has to do is jump on the Piranha Plants to gain coins as they pop out from pipes.

The number of Piranha Plants increases by one every time that they come out, starting at one plant and increasing to nine, filling all the pipes. One coin is earned for each Piranha Plant that is stomped. This minigame can give the player up to 36 coins.
