SpongeBob SquarePants Season 5 Episode 34

SpongeHenge

SpongeBob's holes create a jellyfish-enticing sound when wind blows through them. SpongeBob cannot stand the jellyfish anymore, so he hides in a cave for a long period of time. After a while, SpongeBob makes several stone replicas, which produce better and louder music, to make sure that the jellyfish will leave him alone. He succeeds, so he runs to the Krusty Krab, only to discover that it is already abandoned.
