Junior's Octopuppy - S2.E11

All-Star, Daffney and Galeo enjoy a nice lunch when Junior comes yelling about a watch he has lost. Occy chases Junior off. Then All-Star tells Galeo that Occy used to be Junior's dog. Three years ago, Junior got Occy to protect him from people whom he accuses as thieves. All-Star helps him out by putting Junior's stuff back. On a field trip, Junior is training Occy, who gets stuck. All-Star and Casey help Occy out and Occy takes a liking to him. Then Junior tries to get Occy to track down and catch a butterfly shrimp. Occy leads him to a cave with a giant snorkeater. Occy leaves Junior and goes to All-Star's rescue when he is chased by the Snork eater. From that point on, Occy became All-Star's pet.
