Being the first version that was released, the Game Boy version of the game uses a password-based saving system to save the player's progress. The game consisted of seven floors where various items and parts of Bitsy (Franky's girlfriend) were hidden. Keys and special items were needed to access additional areas to find more body parts and equipment required to resurrect Bitsy.

Franky, one of the many creations of Dr Von Frankenbone, has awoken to find his love, Bitsy, has vanished. Discovering the other evil creations of the castle has taken Bitsy and left pieces of her around the castle, Franky must find his way through the many levels and put Bitsy back together.

Franky can shoot his way past many of the evil creatures, but you must also dodge falling objects and jump over trapdoors to stay alive. Power outlets can re-charge Franky to full health, while lamps must be used to see through the dark dungeons.
