Today Ragey shared with me another obscure cameo: Gachapin Challenge DS. For those curious, Gachapin is basically the equivalent of Japanese Barney. It's a guy in a costume on a show that's for young children. Hudson Soft developed the game and well, here we are.
The main game is a series of minigames featuring Gachapin while there exists a separate mode which is basically Bomberman DS' multiplayer. Funnily enough, he appears right on the cover of the box. How did we ever miss this?
