"Baby Kate and the Imaginary Mystery"
As the smartest kid in his class, Brain really doesn't want anyone to know that he was kept back in kindergarten.
The episode opens up to adult-aged Francine and Muffy doing some investigation at someone’s house. Francine records her voice as she and Muffy are looking for something inside the house. Prunella’s voice is suddenly heard, to which Francine at first mistakes for a talking rake. An adult Prunella reveals herself from the shadows, claiming that she knows a secret about the President. Prunella tells Francine and Muffy to check the files under Lakewood Elementary, stating that the secret occurred in kindergarten.
At the White House, an adult Arthur is telling the president that his history as the smartest president is secure, but the president, revealed to be an adult Alan (Brain), says that the one person who knows his secret is still out there and it would be bad news if anyone found out. At the same time, Francine and Muffy find the files and find out about Brain’s secret, suprising them.
At school, Mr. Haney is hanging up some pictures in a display case while Alan passes by. Alan says he was staying after to set up for the chess club, and notices that his kindergarten teacher, Mrs. Robertson, is retiring after teaching for 30 years. In honorary recognition, Mr. Haney has chosen to hang up the class photos of all the classes she has taught. This scares Alan, and he tries to distract Mr. Haney by having him demonstrate how to make shadow puppets. Alan reaches into the display case to try to take one of the photos, but is pulled away by Mr. Ratburn, failing to get the photo as Mr. Haney locks the display case.
At the Deegan's house, Alan continues to plot how to get the photo from inside the display case. When Prunella asks him why it is such a big deal, Alan panics and closes the window blinds. Alan exclaims that he is in two kindergarten photos and is supposed to be in Prunella’s fourth grade class. Prunella reminds him that she has been keeping the fact that he was held back, and the reason for it, secret all this time. Alan urges Prunella to continue keeping it secret because it would be embarrassing if his friends found out. Prunella says his friends wouldn’t care, but Alan is unconvinced and resolves to get the photo somehow.
Back in his room at night, Alan is still coming up with a plan to get the picture and thinks of a tunneling machine digging underground into the school but ends up in Mr. Haney’s house. He then dismisses that idea and decides to take a nap. However, he ends up sleeping through the night and wakes up late for school the next morning.
At school, Alan is shocked to see that his friends are looking at the photos. It doesn’t take long for everyone to realize that he is, in fact, in two kindergarten class photos. Alan tries to distract them, but Arthur asks why he was in kindergarten twice. Alan panics, and Francine asks if he failed kindergarten. Binky then shows up and asks why it would be a big deal, since he also was held back. Alan lies that was held back due to his intellect. Muffy is skeptical about this, but Brain says that geniuses often get bored and do poor academically as a result. Binky stands by this and tells everyone off, after which they quickly run away. Binky postulates that he must also be a genius too since he was also held back and is bored in class. Alan tries to leave as he makes up the excuse that he has to practice chess, but Binky follows him outside.
At recess, Alan and Binky are playing chess. Binky wins using a move that he made up, and thus thinks that he should have the nickname of “The Brain.” Alan retorts that that is already his nickname, but nonetheless Binky chooses to take the nickname saying that they will find another nickname for Alan.
Later on, Alan and Prunella are walking home from school as Alan explains that he is now nicknamed “The Esophagus.” Prunella remarks on how silly this is, but Alan says it was Binky’s idea. Prunella tells Brain that he should just tell everyone the real reason why he was held back since they will find out eventually. Alan gets really nervous and starts to accuse Prunella about revealing the secret to Muffy, but Prunella retorts that he is getting paranoid and walks off.
In class Mr. Ratburn is handing back exams and scolds Binky for failing with a D-. Binky says he didn’t study since it wouldn’t matter if he failed. Alan points out that he will be held back again, but Binky thinks that would make him even more of a genius. Brain then imagines Binky being held back many times in an aged Mr. Ratburn’s class, due to advice from “The Esophagus.” Realizing that Binky will never graduate by following the logic of his lie, Alan tells Binky to meet him at his house after school.
At the Powers' house, Brain is trying to get Binky to study a vast amount of scientific subjects, saying that there is work involved in being a genius. They go to a science museum and then the library, but Binky continuously shows disinterest and is often distracted.
At the Sugar Bowl, Brain and Binky continue to study. Binky eventually concludes that he may not be a genius after all since he doesn’t like studying as much as Alan does. Binky says that he wore the same clothes for a week since that is what Einstein did, but Alan clarifies that Einstein wore “identical” clothes he had within his wardrobe. Alan then tries to convince Binky that being held back isn’t always the result of being a genius, but Binky starts getting suspicious. Alan panics when he sees Prunella talking to everyone outside, thinking that she is telling everyone his secret, and rushes out to stop her.
Alan tells everyone to disregard everything Prunella told them about him crying a lot and being emotionally unready. Muffy tells Alan that Prunella was actually talking about the latest Henry Skreever book, and wasn't even talking about him in the first place. Alan is embarrassed as he realizes he revealed his own secret and runs off.
Binky is waiting outside, having overheard everything. He remarks that he thinks nothing of it, stating that he still cries sometimes and being held back is nothing to be embarrassed about. Alan realizes that being held back was actually beneficial to him so that could become emotionally ready to move up to the next grade, and as a result he was able to acquire the knowledge to be dubbed "The Brain." The episode finishes with Binky giving Alan his nickname back, and the two proceeding to the Powers' home to study so that they will pass the third grade together.
