Season 1

Misterjaw is having trouble catching fish for dinner. When he sees a pelican fly over and dive down, scooping up his dinner, he thinks that flying is the way to catch a meal, so he tries taking to the air, too! He decides to build himself a set of wings so that he can do this. He also finds that flying is more difficult than he thought! A clever ending adds the perfect touch.

He goes to Pogo Pogo Island to allow the batteries to run down. Tourists win a contest and flood the island.

Two Russians throw a mechanical shark overboard into the sea. Meanwhile, Misterjaw has found a new home: a resident's expensive swimming pool.
