The Battle of Wits by @Kooshmeister (Bill Hiers)

Dr. Zyme, held prisoner in Dr. Viper's swamp lair, attempts to pass the time by playing checkers with Fungusface. However he appears to have learned the hard way that mushroom-cat monsters make very poor checkers opponents: Fungusface is taking forever to try and figure out his next move, while Zyme just becomes really bored.
