To play this, you need a Water Neopet. Before each player's turn, he or she rolls a die. Move this Villain to the strength arena on a 1, to the agility arena on a 2, to the magic arena on a 3, or to the intelligence arena on a 4. It doesn't move on a 5 or a 6. If this moves it to an arena where there already is a Villain, move that Villain to the arena this one came from. When this Villain loses a contest, untap all its rivals.
Enough fungus to rid the world of Neowarts forever!
