Dr. Robotnik's Mean Bean Machine

A Tetris-like game that involved the placing of four same-colored beans adjacent to each other in order to get rid of them. Doing this at the same time is an opponent. Whoever fills their screen to the top with the beans, loses.

Although this is all you need to do to get anywhere in exersize mode, you'll usually need to drop "refugee beans" on your opponent by creating chain reactions. These beans are both annoying and helpful, as they can only be cleared when adjacent to another bean that is being removed, but they are very useful for making chain reactions.

The game itself used characters from the AoSTH continuity, and was basically an edited Puyo Puyo.
