The main character awakens in an underground cavern with no memory of how he came to be there. He finds a village populated by rabbit-like creatures called Mimigas, who are being persecuted by the Doctor. Two of the Doctor's servants, Misery and Balrog, are looking for a Mimiga named Sue, but mistakenly abduct a Mimiga named Toroko. The player's main quest is to rescue Sue, save the Mimigas from the Doctor, and escape the floating island on which the game is set.
