S01E20 — Transistorized Shark

MisterJaw is showing off and scares a fisherman, accidentally swallowing the fisherman's transistor radio. Now with a stomachache, he tries to find a radio repairman. Everywhere that MisterJaw goes, the radio plays a commercial. First, he offends a lady eating ice cream. Then, he "says" just the right thing during a bank holdup. He goes to Pogo Pogo Island to allow the batteries to run down. Tourists win a contest and flood the island.
