Nick and Sally are playing "Pin the Tail on the Donkey", when they wish they had tails of their own! Well, it just so happens that the Cat knows a lot about tails! He brings them to the Jungle of Wagga-Tag-Tail where they meet a number of animals with very different tails. With the help of an ingenious machine, Nick and Sally get to test out all of these tails for themselves and they learn that different tails can do different things!
