SpongeBob's brain is an internal organ that first appears in the episode "Plankton!"

Description

It has many different appearances. It is most commonly pink. Depending on where it appears (including episodes, movies, and shorts), his brain can look and function quite differently.

Role in series

"Plankton!"

Plankton invents a device that allows him to control others' brains. It works at least partially on SpongeBob's brain, although SpongeBob seems to still be in control of his thoughts and some of his actions.

"Scaredy Pants"

Patrick shaves SpongeBob's head down to his brain in order for him to dress like a round-headed ghost.

"I'm with Stupid"

SpongeBob shows Patrick, Marty, and Janet a picture of his brain as a way to prove that he is in fact intelligent.

"Welcome to the Chum Bucket"

Plankton puts the brain into a robotic suit, and it seems to keep its personality even outside of SpongeBob's body.

"Mermaid Man and Barnacle Boy IV"

The Bikini Bottomites go inside SpongeBob after they are shrunk by Mermaid Man's belt, and they see some of his organs including his brain.

"Snowball Effect"

It is mentioned and seen in Squidward's thoughts. When SpongeBob and Patrick claim they will knock each other's brains out in a snowball fight, Squidward imagines the scenario, in which Patrick throws a snowball at SpongeBob and his brain falls out.

"Squilliam Returns"

The inside of SpongeBob's brain is seen in this episode. Inside, there are miniature figures resembling SpongeBob, and there are areas resembling an office and a bathroom. When Squidward pretends to own a five-star restaurant, the miniature SpongeBobs delete all of SpongeBob's thoughts and memories so he will only think about being a successful waiter.

"Bummer Vacation"

SpongeBob very briefly pops his brain out of his head to show mentally he can stay away from work.

"Night Light"

It briefly appears when SpongeBob rolls his eyes in the back of his head to light up the dark inside him.

"Bucket Sweet Bucket"

When SpongeBob fetches water pipes for Plankton's redecoration, one of them goes through SpongeBob's head and knocks out his brain.

"House Fancy"

Before the episode, the brain was borrowed by Patrick briefly, and he gives it back to SpongeBob during the episode.

"Krabby Road"

Plankton has a device that is able to play music from different formats; one of them is "brain," and, in hopes of hearing a song about the Krabby Patty secret formula, Plankton connects SpongeBob's brain to the machine. This results in SpongeBob singing the music selected from the machine dial.

"Penny Foolish"

The brain falls out of SpongeBob's head by Mr. Krabs' search of SpongeBob's 'penny'. They both chas it, showing that SpongeBob can still move and function without it. The brain also has the ability to squirt some sort of liquid at SpongeBob.

"I ♥ Dancing"

SpongeBob claims to have music on his mind, and he takes his brain out of his head. It is literally playing music like a radio, and it even has a radio dial that SpongeBob uses to change the song.

"Stuck in the Wringer"

When SpongeBob takes a shower, the water cleans the brain.

"The Inside Job"

Plankton again goes inside SpongeBob, hoping to get the Krabby Patty secret formula from his brain.

"Kracked Krabs"

In this episode, Mr. Krabs suggests that SpongeBob keep his brain peeled. SpongeBob reacts by literally peeling the top of head to reveal his brain.

"A Day Without Tears"

When Squidward trying to make SpongeBob cry, the inside of SpongeBob's brain is shown. The brain apparently has a large dam built inside it. SpongeBob's tears cause it to collapse and the tears overflow the city of Bikini Bottom, being a metaphor for SpongeBob being no longer able to hold in the tears.

"Earworm"

When Sandy was telling SpongeBob that he had an earworm in his head, the brain is shown.

The SpongeBob Movie: Sponge Out of Water

Plankton once again goes inside it, and it once again is dark pink and smaller. Inside the brain is a gigantic space with SpongeBob's extremely happy thoughts, including the popsicle twins. This huge amount of happiness drives Plankton insane.

"Whirly Brains"

This episode revolves around SpongeBob's and Patrick's brains. They both use their own brains as Whirly Brains, an invention where one's own brain can fly and be controlled in the same way that a normal person would to a remote-control helicopter.

"The Legend of Boo-Kini Bottom"

The Flying Dutchman goes inside it to find a world of colorful happiness, similar to the second movie's version. The interior of the brain drives the Dutchman insane.
