The Slide Whistle song (revealed in credits of The Splinter)
SpongeBob and Patrick get new slide whistles and keep playing them, much to the annoyance of Squidward. He becomes increasingly annoyed as they use the slide whistles as sound effects for everything he does. He eventually has enough of it and flees his house. SpongeBob and Patrick follow after him thinking he's finally playing with them and ignoring his cries to leave him alone. He snaps and grabs SpongeBob's slide whistle and uses it on them. SpongeBob says he has quite an ear for music and soon buy's one himself. Squidward then plays it around the town: first he scares Dennis out of his wits as Dennis thinks he's being annoyed by ghosts and Squidward impersonates a baby and scares Sally out of her wits making her see Squidward as a "baby assaulter", but it annoys a lot of people. Soon they form an angry mob and end up on the warpath against Squidward. Squidward manages to take control over a gasoline tanker truck, destroys the Chum Bucket and the Krusty Krab ,jumps over a row of boats through a ring of fire and drives away from the mob Squidward says he doesn't want to stop but then SpongeBob and Patrick (driving a boat) asks if he is sure he doesn't want to stop then Squidward sees that SpongeBob was trying to warn him a cliff was ahead but there's nothing Squidward can do about it. SpongeBob and Patrick stop just in time but the gasoline tanker truck keeps going and falls off the cliff causing it to explode,much to the joy of the town as they see that Squidward is finally stopped. At the hospital, the whistle gets stuck in his throat and since they don't have the technology to remove it, they just left it there. SpongeBob and Patrick then play around the hospital with the whistles.
