"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 and 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. Next, Jeffy and Bunghole both don't like green beans, he throws his dish of green beans on Mario. And all the sudden, Mario gets Angry at Him and Mario grounds Jeffy before he sent to Jeffy's crib. When Jeffy returned from school, Mario asks how was school for Jeffy. Jeffy said it was terrible. Jeffy goes to the playroom and creates his imaginary friend, 'Bunghole' out of play-doh. Jeffy wanted Bunghole to be red but Bunghole came and said that he'd rather be blue. Jeffy asks if he is real. Bunghole says yes. Jeffy Gets an F- For Failing, Bunghole Asks Jeffy that He Wanted to throw the Desk at his Teacher, but He Didn't want to get in trouble. He Throws his Desk at Jackie Chu which Causes Cody and Junior and the Other Students that he Killed Jackie Chu. Bunghole Laughs and Bunghole asks Jeffy while Jackie Chu Gets what he Deserves. Jeffy Gets Arrested at School While Brooklyn T Guy says that He Killed his Teacher. Brooklyn T Guy Plays and Booger Cracked his Neck While He plays dead. Booger Goes Back to Normal, and gets a Gun but it's Not Real Bullets. He Shoots and Jeffy Freaks out while Bunghole is dead. Brooklyn T Guy and Booger Both Laugh because Bunghole's Dead. Jeffy Started Yelling and Crying Because Mario tells him that Jeffy Would Cheer him 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.
