Story : A small river winds its way across the screen. Plummy drops in and decides to do some fishing. A short while later Plif and Plops arrive. The two think Plummy's idea is good and steal his fishing rod from him. Disappointed he crawls under the bridge, but he's already got a few good ideas. He turns himself into a beaver and starts gnawing at the bridge on which the other two are sitting so that they fall into the water. This doesn't impress the others at all so Plummy decides to jump on to the river bank as a toad and hangs their bits and pieces from the rod. When he then turns himself into a shark, Plif and Plops are so terrified that they disappear off the screen. Plummy can now fish in peace.
