Colo the cougar and her friend Ruff jump and play together, but they find that Ruff can't jump nearly as far as Colo. Ruff doesn't have a long, swishy tail like Colo does, to provide balance on long leaps. Ruff is a bobcat and his tail is much shorter. He is sure that something is wrong with him. The sympathetic Colo suggests that they go find a tail that Ruff would like better, so off they go. As the two kittens explore the variety of tails worn by other animals, they make the best discovery of all.
