Season 1: Episode 22

Dogtanian and Pip are still stranded on the island. Pip is hungry so they walk inland to find some food, they find some fruit which Pip knocks from the top of a tree. Before Pip can tuck in they hear a strange noise and go to investigate. They find a "monster with a tail where its mouth should be", also known as an elephant stuck in the mud. They go in to rescue it, Dogtanian doing most of the work, but before it's out a crocodile comes in. Pip tries to catapult a rock at the croc, but launches himself onto its back, Dogtanian tries to duel it but has to run and is caught in its mouth. The elephant uses his trunk to throw some trees on the croc and saves the day.
