|aSequel to: Dinosaur rescue 7 : Scuto-stickysaurus.
|aAnother hilarious adventure for Arg, the evolved Neanderthal boy, and his T-rex friend Skeet, the talking dinosaur. Arg's tribe is bartering with the Nn-Grrrdy tribe. While Arg is attempting to hide his stuff in a burrow he gets stuck in a muddy cavern underground. Is Arg going to be able to get out before he's eaten by a bunch of hungry (usually-friendly) saltopuses?
