When life on the Tucker farm is disrupted by the arrival of a peacock, whose shrieking and strutting bring many welcome visitors, the hens complain that they are doing all of the work until the hound suggests a trade.

The Good Beasts of Avantia have been taken hostage by the Evil Wizard Malvel. Each is being guarded by a new evil Beast in the Dark Realm. In order to rescue Tartok, Tom must go against Kaymon the Gorgon Hound, a Beast unlike any he has faced so far on his Quest. Kaymon prowls the ruins of a forgotten castle. Will Tom be able to defeat this menace and come one step closer to stopping Malvel forever?
