Beyond the Valley of the Dinosaurs.Harvey is invited by Potamus to relax in his new hot tub, wearing a pink shower terry that Potamus has told him to put on. Potamus instructs Harvey to "hit the jets" on the tub and when Harvey does so he is enveloped in a blue light and sucked into the swirling waters of the tub. Potamus follows Harvey, trying to retrieve his hoagie. Harvey and Potomus rematerialize in what appears to be the Stone Age. Harvey attempts to call Peanut (who seems to be hosting a Lamaze class in Potomus' office) but can't get a clear enough signal on his mobile phone. Harvey is caught by a group of neanderthal cave men who believe he's the "pink manbird" (because he's still wearing the shower terry) their oracle had foretold would bring them pestilence and drought. When Potomus appears they mistake him for their pink hippo helmet-wearing God, which Potomus gladly embraces.
