Backyardigans - 54 - Caveman’s Best Friend

It’s a pretty exciting day in the stone-age town of Rockville. AUSTIN is getting a new pet dinosaur from pet shop owner UNIQUA. While playing, Austin lets his dinosaur off his leash and he runs away. Uniqua tells him the only way to get him back is to whistle. That would be easy enough if Cop PABLO or fireman TYRONE knew how to whistle. Will Austin get his dinosaur back or will they all meet their fates in one of the local tar pits?
