| Please note the following:
"Jeffy's Birthday Surprise!" is the 397th episode of SML Movies.
The video starts out with Jeffy arriving on the red couch that Mario is watching TV on, wearing the same birthday hat that he wore the previous year. He then asks Mario if he knows what day it is and Mario responds that he doesn't. Jeffy then explains to him that it is his birthday. Mario realized what day it is and doesn't want to admit that he forgot his birthday. Mario explains how they're not celebrating his birthday this year because he's grounded.
Jeffy gets mad and asks why, so Mario goes into the kitchen, smashes a bowl of fruit loops, and returns to explain to Jeffy why he's grounded so he is grounded. Mario goes to Chef Pee Pee to bake him a cake. However it is his break day. Mario ask him anyway but he starts laughs at him, and Brooklyn T. Guy comes to the house since Mario called him. Mario tells him that he needs him to make a cloning machine to clone Chef Pee Pee since he is refusing to make a cake for Jeffy's birthday.
Like Chef Pee Pee, Brooklyn T. Guy uncontrollably laughs and Chef Pee Pee joins in with him after telling him what Mario said to him as well. Mario is freaking out wondering how he is going to clone Chef Pee Pee when Cody comes in with a nerf gun that he says is a clone gun. Mario bought the clone gun for $20. While Chef Pee Pee talks to his brother, Mario shoots Chef Pee Pee with the "clone gun" and realizes that it is just Nerf gun. He starts yelling at Cody when Cody pulls out another "clone gun" which is revealed to be just a water gun. Mario is about to run out when Cody gives Mario the real clone gun.
He shoots it at Chef Pee Pee and out comes Chef Poo Poo. Mario asks him to make the cake while he went shopping. He instead made a big mess in the kitchen, which made Mario start freaking out. He then went to Brooklyn T. Guy, who told him that he could just buy it at Walmart, so he did. They get in an argument about the placing of the numbers since Jeffy and Brooklyn have the same birthday and Jeffy is going to be 14 and Brooklyn is going to be 41. When Jeffy comes in, Brooklyn T. Guy secretly switches the placing of the numbers.
They then started singing Happy Birthday, but whenever it got to “you” Brooklyn would say "Me!" and at the end he blew candles before Jeffy got a chance to. He wished that it was not Jeffy's birthday anymore and after that he ruined the cake, hit the piñata off the table, took the gifts, and the video ends.

- It is also his first and only appearance in 2018.
- Additionally, Chef Pee Pee's clone being Chef Poo Poo could possibly be reference to said video.
- This is the 3rd and final time Cody appears without Joseph or Junior in a 2018 video.
- This is another video to show Cody with his clever inventions.
- This is one of those videos where it got panned by many fans, most likely because of the out-of-character behavior of Brooklyn Guy, and Chef Pee Pee refusing to help Mario and just laughing at him instead.
- Jeffy gets sent to the corner and starts swearing, just like he did in "Drawing Jeffy!".
- This is the second time Cody and Mario interact the first time was "Jeffy's Taco Tuesday!".
