Flash, Dale and Thun are cut off from their escape and menaced by a massive reptilian cave-dweller, which threatens to devour Dale until they manage to distract it. Even this, though, only delays their seemingly inevitable death until another creature arises, just as hungry, and attacks the first. The two monsters bite and struggle, the creatures that were once their prey driven from their minds, until they finally drag one another off of a cliff and into the abyss.
