It's Just a Matter of Slime - S2.E9

All-Star meets a kelp helper who is facing a lot of trouble because of what he is. All-Star then makes friends with the kelp helper, but the grandfather is uncertain about all this. This friendship is ruined when Junior insults them. The Kelp helpers all pack up and leave. Because of all the kelp helpers leaving, Snorkland is all full of algae. Everyone has to clean up and it's all the Governor's fault. All-Star goes to the kelp helpers and apologizes to them, but they expect an apology from the governor himself. It takes a giant snorkeater terrorizing Snorkland to set the governor straight. The Kelp helpers really did make a great contribution to Snorkland after all.
