"Bowser Junior's House Party!" is the 519th video of the SML Movies.
Bowser Junior throws a party!
Junior, Joseph, and Jeffy were playing with cars until Jeffy cries and accused Junior of breaking them. Then someone was at the door.
It was Roy who showed up and Junior and Joseph talked about for a while and Roy says he is throwing a party and Junior and Joseph asked if they were invited but Roy said no and furthermore said they were lame and was only here to invite Jeffy and took Jeffy to the party.
Junior and Joseph talking about not being at the party and they call Cody who turned out to be at Roy's party as well Junior and Joseph eventually got jealous and Cody asks Roy if he invited them and he said no and that their lame.
Junior and Joseph later disguise themselves as wealthy people from England in an effort to get into Roy's party with Joseph having a British accent and Junior having an American accent. They knock on the door and ask Roy that they were here for something besides the party causing Roy to get suspicious.
After getting kicked out the duo realized that they can throw their own party.
They get their clown suits and after getting into a short fight decided to do a weird challenge.
After that Junior and Joseph were playing some games but two of them were lame and the Peppa Pig one turned out to be really good but their own party turned out to be lame after they called Cody on the phone.
Sometime later Jeffy appeared with Karen saying that Roy broke into a house and got busted and Mario eventually arrives to pick Jeffy up and was ultimately enraged to see that Jeffy went to break in a house. He grounds Jeffy for this and Junior and Joseph learned their lesson as the video ends right there.

- This is the first episode since "Joseph's New Shell!" that was not uploaded on either a Wednesday or a Saturday. This is likely because Logan changed his uploading schedule.
- Roy would have been arrested instead of Jeffy because Jeffy didn't do anything wrong. Roy invited Jeffy and Cody, so Going into a party isn't a reason to get arrested. They just got invited. So Roy would be arrested, Not Jeffy And Cody. And Mario would unground Jeffy. Karen probably arrested Jeffy, due to her stupidity or to escort Jeffy home. However, it's quite common for people to get arrested at parties even if they don't drink or anything like that, so that could likely be the reason. Also, Roy likely got arrested off-screen.
- Although it's never stated, its likely Cody was arrested for the same reason detailed above as Jeffy, and Cody may or may not have gotten grounded since The Cover Up!
- This is Roy Gethard's first speaking appearance.
- This is the third time Logan makes references to Roy Gebhard's real-life incidents like the Super Bowl tickets and the Chilly breakup.
- It's been over 3 years since "PJ Crenshaw" was mentioned, last mentioned in Chef Pee Pee's Kids.
- This is the third time Jeffy gets arrested. The first time being "Jeffy the Rapper!" and the second being "Jeffy's Imaginary Friend!".
- "Eminem" sounds like "M&M's", hence why Junior faked the rapper being there by having the candy instead. Interestingly enough, in real life, Eminem did actually collab with M&M's.
- This is the first time in which Karen physically appears without her husband Brooklyn T. Guy.
- This is also the second appearance of Karen as a cop, the first being Jeffy's New Friend!.
- It is also the first time in SML canon where Karen works as a cop.
- Junior's disguise name "Benedict CucumberBack" is a reference to English actor Benedict Cumberbatch.
- This was released on the same day the PlayStation 5 (PS5) was revealed.
- This is the second video where Joseph uses a British accent, the first being "Bowser Junior's SICK Pool Party!".
- This episode is the first to introduce Butterball, one of the many puppets that were sent to Lance and Logan by Silly Puppets.
- It is revealed in this episode that Cody does not like the TV show Drake and Josh and considers it lame.
- However, it could be implied that Junior and Joseph both love Drake and Josh and they could also be huge fans of that show too.
- The likely reason why Roy invited Cody and Jeffy and not Joseph and Junior could be that Roy thinks they are cool due to Cody possibly giving him test answers and Jeffy has done things that Roy presumably would consider cool (cursing out Jackie Chu, beating up Bully Bill, etc), and that Junior and Joseph are considered lame for being turtles, specifically Koopa species. Cody however is a Magikoopa (meaning he counts as a turtle), however, but Roy may not be aware of this because of how Cody wears a robe instead of a shell.
- Roy Gethard breaking into another house could possibly be referencing Chilly breaking into Logan's house and stealing some stuff.
- In the scene where Roy who showed up at the door, Jeffy was completely silent, due to Lance being busy voicing Roy.
- Cody mistook Billie Eilish for a male as a joke, since Billie (Billy) is mainly a guy's name and Cody is a homosexual.
- This episode reveals that Screwball was recently released from jail.
- This episode features a deleted scene before the introduction of Butterball, where Junior and Joseph wonder what every party needs; Joseph suggests girls but Junior reminds him that they don't know any girls. Junior thinks of getting a clown, and Junior and Joseph argue about who knows the better clown, until Junior calls Joseph a clown and they both walk out of the room.
- The SML question for this video was the same one from "Cool Cody!".
- At 12:33, Lance's ear can be seen for a split second.
- At 0:29, Bowser Junior realized the doorbell rang, but the doorbell sound didn't play until later at 0:30; the doorbell sound played too late.
- While on the call with Cody, Chris voices Roy instead of Lance due to the party taking place inside his house. Roy's voice is noticeably different from how it was earlier in the video
- The thumbnail is misleading because in the thumbnail, it looks like Junior and Joseph are going to dance for some music with a boom box. However, in the video, they didn't dance for some music.
