Guid the mouse through the tunnels without touching the lava. But a secret combination of letters you unlock at the end of the game, gives you a lava solidifier that allows the mouse to tunnel through the lava! The notice that you have activated the solidifier will flash three times. Also if you get far enough you'll find more combinations of letter that unlock more cheats, for the Shrink Lightning type in M, I, N, and Y at the same time.
