Corky and Jo-Jo are travelling through and they see the Seaweeds trying to release the Big Ooze, which will destroy Snorkland. They get there too late and the Ooze is set free. The Ooze takes over Snorkland and uses electricity to get big. The Ooze also tricks the Seaweeds into getting in a cave where he has captured the Snorks. All-Star brings all the Snorks together to stop the Ooze. Bigweed agrees to help them out against his will. The Snorks get out of their jail by tricking the Ooze, and they swim for a sunken ship. They use his electric power to power the ship and make him shrink down to size. When Bigweed reneges on his word, the Snorks get him.
