Gachapin Challenge puts Gachapin in a Hudson classic
The latest game to bear the character's amusing likeness is Gachapin Challenge DS, which is a 20-sport collection. We're pretty sure running or otherwise exerting himself in a sporting exercise would kill the guy in the Gachapin suit, but it's safe on DS. Some of the events include hovercraft racing, karate, scuba, and mogul skiing.
Gachapin Challenge also has a "Gachabomberman" bonus mode comprising a traditional Bomberman game for up to four players, but with sleepy-faced Gachapin in the place of Bomberman.
