From the rules: The Slime Monster has invaded the town. You've got to stop him! You must get from the High School to the Armory, pick up a land mine and knock the Slime Monster over. But be careful that the Slime monster doesn't knock you over with his slime.Movement is directed with a spinner. Each spin is used twice: once for the player and the same amount for the monster. The players try to manipulate the monster so that he winds up standing over an opponent. He then 'slimes' the player and moves. If the slime covering the player causes the player piece to fall over, the player must start again. Yuck! - BoardGameGeek
