Plot
The player's character must save his girlfriend, who was kidnapped by a young girl. The backstory differs slightly between the Japanese and American versions, although the in-game presentation is the same regardless. In the American version, the player's character is named Bon-Bon and the girl he must rescue is a Princess named Candy, who is trapped in her own dream. In the Japanese version, the main character is named Carton and the girl he must rescue is merely his own girlfriend, Jenny, who has been kidnapped by Carton's younger sister Quinty (the titular character in the Japanese version).

Gameplay
The game can be played by a single player, or by two players co-operatively. The players' characters are a blue and a green-colored boys in a vest and cap. Each level consists of a single room composed of a 5 by 7 grid of floor tiles surrounded by a boundary wall. At the beginning of each level a number of enemy dolls appear and start to wander around, attempting to collide with the player. The characters have the ability to "flip" the floor tile they are standing on or adjacent to in order to propel enemy dolls away, as well as revealing new floor tiles underneath. Enemies can be destroyed by flipping them into a wall or impassable block. The player(s) must destroy every doll to complete the level and move to the next one.
