List of characters

Sour Note is a superhero alter-ego of Squidward Tentacles who appears in The SpongeBob Movie: Sponge Out of Water.


Sour Note has a muscular body similar to Squidward's "handsome" body in "The Two Faces of Squidward." He has matching piano gloves and boots and a mask with eighth notes on each side.

He has a clarinet that he can summon, which takes its appearance from a clarinet in real life.


Sour Note has made one appearance during The SpongeBob Movie: Sponge Out Of Water. He and Invincibubble's team of Superhero Friends save the Krabby Patty Secret Formula from the greedy hands of Burger Beard the Pirate, who uses the book to get the formula, since whatever is written in the book becomes real.

He first uses his clarinet as a full scale attack on Burger-Beard, who resists the loud music. Then later, during the chase, he uses it in a last-ditch attempt to keep the book away from Burger-Beard before collapsing in exhaustion. He does not appear until after Plank-Ton saves the gang and retrieves the formula. Squidward wishes to stay in this form forever, but SpongeBob returns everything to normal via the magical book, although allowing Squidward to keep his "rock-hard abs."
