Plot[]
Digeri Dingo wants Taz to carry him up a mountain so he can talk to the wise man atop it. Taz refuses until Digeri tells him there's food up there. Taz keeps climbing and pulling Digeri up behind him, but a playful goat keeps butting him off. After Taz falls several times, Digeri asks the goat for help and ties a rope between it and them. It's an extremely bumpy ride, but at last they make it to the top. Digeri seeks counsel from the wise man. However the wise man removes his hooded robe and reveals that he is the goat, who butts them off the mountain once more.
