What you have to do is whack as many piranha plants as you can. Each Piranha Plant you whack gets you 1 coin, the most coins you can get is 30 (?). If you fall off, the game automatically ends. Luckily, if you're about to fall, there's these springs to bring you back on, but there not all over the floor. Also, it's one of those old Mario Party 1-player games. The title was a spin-off of "Whack-a-mole", it was cleverly put in. =P I always got around 24-25 coins while playing this game, how about you?
