The Ugly Yuckfish - S2.E14

The Snorks visit the Undersea Fish Exhibits and are looking for the legendary Rainbowfish. Daffney doesn't want anything to do with it because it might mess up her chances for a beauty contest. Daffeny is soon pursued by a Yuckfish. Junior scares it away by taking pictures but the Yuckfish follows them as they leave. Daffney loses her purse and the Yuckfish finds it for her. The Yuckfish really likes her, but Daffney doesn't give him the time of day. She finds him a good home with a Snork rancher, who disgracefully turns the Yuckfish into a sideshow act. The Snorks break him out by pretending to be a circus trainer with a giant fish (Daffney, Casey, and Tooter). The Snorks then take Daffney to the beauty contest where she wins. The Yuckfish joins her on stage and Junior starts laughing and making fun of it. Daffney defends it by saying that it is beautiful and to everyone's surprise, the Yuckfish turns into a beautiful Rainbow Swan fish!
