Bomberman and Max have been shrunk by the evil Mujoe's Mini-Mini Device. They must take revenge on him and his Hige Hige Gang, and, hopefully, return to their normal size.

The gameplay is similar to most Bomberman games, where Bomberman and Max lay down bombs to destroy enemies, blocks, etc. Unlike past Bomberman games, however, there is a lack of the classic multiplayer, instead featuring a more Pokémon-like game. In this game, there are many monsters that Bomberman and Max can acquire and use to their advantage.

Both games are more or less the same, although they both have some extra levels and different charaboms.
