"Jeffy's Imaginary Friend!" is the 420th episode of SML Movies.
Jeffy has no friends so he makes an imaginary friend!
The video starts off with Jackie Chu teaching the class about dodo birds. Jackie Chu explains that the DoDo bird died because nobody liked it since it smelled like Poop. Jackie then teaches the word Extinct. He says Extinct means no longer existing. After that Jackie Chu gives an example of Extinct: Girl in China soon to be extinct. Bowser Junior then mentions Joseph's Mom and Joseph's Dad are extinct. (They actually are not) Joseph starts crying when he got reminded of his Mom's fake death. Jackie Chu explains why the play-doh was in front of everybody. It was not for them to eat. Everybody was upset when Jackie Chu said that. It was for them to do their partner project on a made up extinct animal. They were supposed to pick a partner and combine their play-doh to make up an animal that could have gone extinct. Bowser Junior gets happy when he finds out he can choose his partner to be Cody. Joseph says he wanted to be Bowser Junior's partner but instead Bowser Junior decides that Joseph should be partners with Toad. Toad agrees. Patrick makes his pink play-doh a long tongue and puts it in his mouth before Bully Bill asks him to be his partner. Patrick agrees. Jeffy raises his hand and says he does not have a partner. Jackie Chu says that Jeffy has no partner because Jeffy does not have any friends and then tells Jeffy he gets extra play-doh and throws it onto his desk. At home, Jeffy tells Mario that his day went terrible then tells him what happened at school. Mario tells Jeffy that he does not have any friends because he wears a diaper and he is 14 years old. Mario then tells Jeffy to make friends. Now, Jeffy is creating an Play-doh animal to look like Bunghole, a blue furry monster with green hair. Bunghole comes right behind Jeffy after he wishes that he was red and they become friends forever. In the game room Jeffy shows Bunghole to Mario but he does not see him. Mario eventually calls Brooklyn Guy. Brooklyn Guy tells Mario that Bunghole is Jeffy’s imaginary friend. Jeffy denies it. Dinnertime, Jeffy and Bunghole are served green beans. Bunghole uses his demonic voice to tell Jeffy to throw the green beans at Mario. Jeffy throws his dish of green beans on Mario. Suddenly Mario gets furious at Jeffy. He grounds Jeffy by sending him and Bunghole to the crib. At school, Chu looks at the projects. Patrick and Bully Bill made a piece of poop with bubble gum all over it. They receive a D+. Bully Bill accepts the grade. Bowser Junior and Cody made a dog with a big crank. They receive an A+. Toad and Joseph made a frog with chicken pox on it’s back. They receive a B- for not covering the whole body with chicken pox. Chu goes over to Jeffy. His project is nowhere to be seen. Jeffy gets an F. Bunghole is furious. He forces Jeffy to throw the desk at Chu, but was worried that he might want to get in trouble. He throws his desk at the teacher anyway which causes Cody, Junior and the other students shocked that he assaulted Jackie Chu. Bunghole laughs then congratulates Jeffy. At home, Jeffy is wearing handcuffs which makes Mario really furious. Brooklyn Guy shows up and tells Mario about the incident. They attempt to arrest Bunghole but Brooklyn T Guy plays and Booger cracks his neck while playing dead. Booger goes back to normal, and gets a pistol but it's imaginary bullets. Booger shoots and Jeffy freaks out while Bunghole is dead. Brooklyn Guy and Booger both laugh because Bunghole's dead. Jeffy starts screaming and sobbing. Mario tells him that he would cheer Jeffy up, and the video ends.

- This is the first appearance of Toad and Patrick in 2019.
- This is also the first appearance of Booger and Bunghole.
- The ending where Mario says that Jeffy is his best friend is similar to the ending of Fountain Of Youth! where Junior says to Bowser that he's still cool to him even when he's old.
- Jeffy made Bunghole out of Play-Doh and suddenly came to life, similar to how Junior and Jeffy made Gumbo out of Play-Doh and did the same thing in Drawing Jeffy!.
- This video introduces the idea that Jeffy is a fan of Naruto.
- Bunghole sounds a lot like Luigi, and Booger sounds similar to Kirby. This is because all 4 are voiced by Anthony Miller. Coincidentally, Kirby and Luigi are main/recurring characters on Anthony's channel, KirbStomp.
- At 1:02, a bit of Lovell's mouth can be seen on the top right while Toad asks Joseph to be his partner.
- When Junior says Joseph's parents are extinct, however, it was revealed that in Joseph's Mom! that Joseph's Mom faked her death. Although, this is not the first time this has happened, and may just be a simple inconsistency. Junior may however be referring to how his mother's love for Joseph is extinct.
- When Jackie Chu asks Bowser Junior and Cody how their big dog has gone extinct, extinct is instead pronounced ex-tinc.
