Little Rok and Ork are fishing when they run into a boy named Norg of the Hill People. Norg is from a neighboring village and is looking for Mightor because Kragor and his Cavern Creatures have attacked his village. Little Rok tells Norg that he is Mightor and the two set off to run Kragor out of his village. Tor sees them and after hearing what they are doing turns himself into Mightor and is off to do battle with Kragor again.
