The dinosaur friends are puzzled to find that their waterfall is not working. They set off up the riverbed to investigate but Flapper's non-stop eating and Nutter's crashing add to their troubles. When a T-rex attacks them, he releases the boulder holding the water back and the friends float back home. They escape the T-rex by going over the waterfall.
