A classroom teacher introduces a new class pet, a goldfish named Crab Cake Hero, to teach the students about responsibility. The students are excited, and Junior and Penelope both want to take the fish home first. However, the teacher decides to let the fish choose, and Crab Cake swims towards Junior.
Junior takes the fish home but ends up dropping it down the sink, and a plumber is called to retrieve it. Unfortunately, the plumber accidentally turns on the garbage disposal, killing the fish.
Junior tries to replace the fish with a goldfish cracker, but Cody suggests getting a real fish from a pet store. Junior returns with a new, larger goldfish and tries to pass it off as the original Crab Cake, which has grown. The teacher is skeptical but doesn't expel Junior.
Penelope, who was supposedly sick, sneaks into the classroom and is caught by the teacher. The teacher decides not to expel Junior, and the episode ends with the class continuing their lesson.
