After buying a new product called "Whirly Brains", SpongeBob and Patrick fly their brains around like drones until their, as well as everyone else's, brains are captured by a grumpy old fish.
Vincent Waller confirmed the episode on Twitter on October 9, 2015. The episode was originally scheduled to be released in the summer of 2016, but was pushed back to the winter season. Vincent Waller has also confirmed the episode will be a half-hour episode..
- When this episode premiered, it was paired up with "Scaredy Pants."
- In France, Ed Asner was accidentally credited as executive producer.
- This is the first time the Jewelry Store appears within the TV series. The store previously only appeared in the video games SpongeBob SquarePants: SuperSponge and Employee of the Month.
- This episode reveals that Mr. Krabs and Mrs. Puff have been secretly dating, indicating that since the events of the episode "Krusty Love," they never stopped seeing each other. In spite of this, in the episode "Summer Job," Mrs. Puff believed Mr. Krabs was asking her on a date as if they've never dated before. However, they may have been trying to hide that they were dating from SpongeBob.
- In the back alley where Mr. Krabs and Mrs. Puff are having a date, the walls of one of the buildings has the word "Sharks" and "Pods" written in graffiti, referencing the Season 9 episode "Sharks vs. Pods."
- The fourth wall is broken at the end of this episode when Squidward runs and looks at the camera yelling "You're next!"
- Plankton is the only main SpongeBob character who does not appear in this episode.
- On DirecTV, this episode and "Mermaid Pants" are listed as the 29th episode of Season 9 rather than the first episode of Season 10.
- The title is a possible reference to Whirlybirds.
- Whirly Brains could be 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 "A Sucker For The Suck-O-Matic" from Rocko's Modern Life, 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.
- 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 wearing no shirt.
- When Patrick starts up his Whirly Brain, he's holding the controller upside-down, but in the next shot, he's holding it correctly. In the next scene, it's once again upside down, and in the rest, including the very next shot, it's being held correctly.
