The episode begins at SpongeBob's house, where 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. 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. After literally losing their minds, SpongeBob and Patrick (the latter seemingly figuratively losing his) begin to panic, as they cannot find their brains. With an idea, 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 beings.
Sandy is about to threaten the old man, who immediately cries out an apology before revealing he hoarded the toys because he can't stand seeing everyone have fun while he stands there with his cane. However, Sandy and SpongeBob hook the latter's propeller onto the old man so he can fly in the air too.
It frightens the lady fishes, as they run around in circles at the Shady Shoals Rest Home building. Squidward then appears, going crazy thinking the Martians have landed. He ends the episode telling the viewers "YOU'RE NEXT!" twice.
On December 18, 2015, Vincent Waller tweeted some early production work of the first season 10 episode. As noted on a photo of the script, the first draft was dated November 30, 2015 and the board draft December 4, 2015.

‣ Straight from Hell 10 - Gregor Narholz [The ending]
- This episode is available on the SpongeBob SquarePants Vol. 16, The Legend of Boo-Kini Bottom (UK version only), The Complete Tenth Season, and SpongeBob is a Doctor DVDs.
- The title card is similar to that of "The Inside Job," as both include brains as the background.
- SpongeBob's eyeless design in this episode is similar to his eyeless design in "Food Con Castaways."
- When SpongeBob and Patrick's whirly brains fly through a bush and make a SpongeBob and Patrick-shaped topiary, it resembles some stock artwork.
- This episode reveals that Mr. Krabs and Mrs. Puff have been secretly dating for the last 16 years, 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 have never dated before.
- In the back alley where Mr. Krabs and Mrs. Puff have 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!"
- This episode marks the first appearance of the Jewelry Store within an episode of the series. The store was previously seen in the tie-in video games SuperSponge and Employee of the Month.
- This was Bob Jaques' first episode as an animation director.
- This is the fourth appearance of Shady Shoals Rest Home without Mermaid Man and Barnacle Boy. The first was "Doing Time," the second was "Gramma's Secret Recipe," and the third was "Bulletin Board."
- This episode and "Mermaid Pants" were the only season 10 episodes to premiere in 2016.
- Whirly Brains are a take on remote-control helicopters and toy drones.
- SpongeBob and Patrick getting hypnotized by the Whirly Brains commercial is similar to what happens to Rocko and his friends in the Rocko's Modern Life episode "A Sucker for the Suck-O-Matic."
- Patrick's line "M-O-O-N! That spells moon!" references Stephen King's novel The Stand and its miniseries adaptation, which also featured Bill Fagerbakke in the role of Tom Cullen.
- During the original United States premiere for this episode on October 15, 2016, Bob Jaques was misspelled as "Bob Jacques." This was corrected on the digital releases two weeks later on October 29, 2016, when the sister episode segment "Mermaid Pants" premiered. It is also corrected on all American reruns, all international airings, and on The Complete Tenth Season DVD.
- In the French dub, Ed Asner was accidentally credited as executive producer.
- On airings of the German dub, the title card is mistakenly cut out.
- When SpongeBob and Patrick are fighting with the TV, a picture of a fish is shown, despite being unplugged.
- In the SpongeBob and Patrick-shaped topiary, SpongeBob's eyelashes are missing.
- 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, the controller is once again upside-down, and for the rest of the episode, including the very next shot, it is being held correctly.
- When Squidward sees Patrick's brain floating up and down, he screams out "Aliens from Mars!" while wearing a shirt, but in the next shot, he is naked and not wearing a shirt.
- When SpongeBob and Patrick shout "Whirly brains are go!," their moving mouths freeze as a bubble transition comes on the screen.
- In a shot of the angry old timer's house right before Sandy comes in, there's a sign that says, "No Trespassing." However, the word "Trespassing" is misspelled as "Tresspassing" with an extra S added in.
- There are few scenes when Patrick's eyebrows disappear.
- When the fish on the right drinks the tea, the tea begins to overlap.
