Veloci creates a herd of mutant-moose-a-saurs, but before the Dino Squad can trap and de-ooze the creatures the Squad must first overcome their fears (real and imagined) in order to survive a night in the wilderness.

Rodger's big head causes big headaches when the Dino Squad winds up on a deserted island and their attempts to de-ooze an out-of-control gorilla-saurus are thwarted by Rodger's out-of-control ego.

Buzz mistakenly brings a mutant garter snake onto a passenger train and the Dino Squad must race to catch the train before Buzz and the snake are captured by Victor Veloci.
