Grok steals the Golden Rok which has the ability to control any animal. It falls out of his pouch as he is leaving and hits Li'l Rok on the head. While fighting a dinosaur, Li'l Rok discovers the power of the Golden Rok. As he is experimenting with it, Grok returns and steals it back. Tor hears animals fighting in the area that Li'l Rok had headed; he turns himself into Mightor and heads off to investigate.
