"Whirly Brains" is a SpongeBob SquarePants episode from season ten. In this episode, SpongeBob and Patrick get hooked on the latest fad – flying your own brain like a tiny drone.



At SpongeBob's house, SpongeBob and Patrick are bored playing with sticks but an advertisement appears that attracts them to a new toy, called the Whirly Brain, which involves one detaching their brain from their head and putting it on a propeller. Intrigued, they buy the toy and fly their brains around town to spy on citizens and pull pranks.

After getting eggs thrown at them, a kid tells SpongeBob and Patrick that everyone has Whirly Brains and not just them.

Whirly Brains 097

Patrick, SpongeBob, and the unnamed kid race but SpongeBob and Patrick's brains land into an old man's house and he takes them as his own. SpongeBob calls Sandy on the phone and she uses a missing brain detector to find the brains.

Sandy's detector leads to the same old man who found their brains. She asks kindly but the old man is snoring. However Sandy just walks in and they try to look for the brains. The floor creaks and he wakes up, but Sandy puts a fight with the old man. SpongeBob accidentally trips onto the barrel, and all of the brains fly free, and all of them go back to their original being

The old man cries because he doesn't get to have fun but Sandy and SpongeBob hook the latter's propeller onto the old man so he can fly in the air too.

Cultural references

  • The title and the product featured in the episode is a possible reference to Whirlybirds.
  • Whirly Brains are a reference to remote-control helicopters and toy drones.
  • The part where SpongeBob and Patrick are seen "hypnotized" to get the "dangerous but popular" Whirly Brains on TV might be a reference to the Rocko's Modern Life episode "A Sucker for the Suck-O-Matic," where Rocko, Heffer, and Spunky are also hypnotized to get a dangerous product that later populates the neighborhood, the Suck-O-Matic.
  • Patrick's line "M-O-O-N! That spells 'moon!'" is a reference to Stephen King's novel The Stand and its miniseries adaptation, which also featured Bill Fagerbakke in the role of Tom Cullen.
  • The episode references the FAA putting strict regulations for drone use.


  • On DirecTV, this episode is listed in "Season 9, Episode 29," instead of "Season 10, Episode 1."
  • When Squidward sees Patrick's brain floating up and down, he screams out "Aliens from Mars!" wearing a shirt, but in the next shot, he is not wearing a shirt.
  • When Patrick starts up his Whirly Brain, he is holding the controller upside-down, but in the next shot, he is holding it correctly. In the next scene, it is once again upside-down, and in the rest, including the very next shot, it is being held correctly.
  • On early airings of the German dub, the title card is mistakenly cut. This was fixed on later airings.
  • When SpongeBob and Patrick shout "Whirlybrains are go," the mouths stay the shape they were at the end of the phrase until the bubble wipe cleans the screen.
  • In the French version, Ed Asner was accidentally credited as executive producer.
  • On the shot of the old timer's house, the sign "No Trespassing" is misspelled as "No Tresspassing."
