| Please note the following:
Bowser Junior's Big Spill! is the 297th video of the SML Movies.
Bowser Junior and Joseph play basketball outside and Joseph scores by distracting Bowser Junior who says that is cheating. After this, Bowser Junior complains it is too hot outside, so they decide to play basketball inside. Joseph asks Bowser Junior if they won't get in trouble for breaking something. Bowser Junior answers that won't happen with his skills and then fails to throw the basketball in the hoop. Joseph says he sucks and Bowser Junior tells Joseph to try it and he manages to score.
Bowser Junior is thirsty and gets something to drink. He wants to take a bottle of Hawaiian Punch with him and fills his cup in the living room, but Chef Pee Pee tells him not to because he will spill over the white furniture and his dad will get mad. Junior says he won't spill and takes the bottle to the living room.
Bowser Junior asks Joseph to hold the cup while he pours it. He does not spill anything. After this, Joseph scores and Bowser Junior bets he can score from the balcony. Unfortunately, he misses and the ball hits the bottle and the cup making a mess of the couch. Joseph brings up the idea to blame Chef Pee Pee. Bowser Junior puts one of Chef Pee Pee's shirts, a spatula and a note that says "I did it" Signed as "Chef" followed by a drawing of a penis at the couch. Then, he asks Bowser, who just watched Charleyyy and Friends, where Charleyyy injured himself attempting a back-flip, to come look. Bowser believes his son and asks him to give a football to Chef Pee Pee. Chef Pee Pee gets the football and Bowser charges him in a football uniform.
Chef Pee Pee asks Bowser why he did that and Bowser shows him the couch. Chef Pee Pee tells him it was probably Bowser Junior but then Bowser shows the evidence Bowser Junior left. Later, Chef Pee Pee asks Junior why he blamed him but Bowser Junior acts like he doesn't know anything.
Chef Pee Pee takes revenge by telling Bowser someone is at the door to go in his room and spills lasagna all over his bed and putting a note down saying "It was me" signed by Junior and another drawn penis. But Bowser gets back quick enough to see Chef Pee Pee ruining his bed, and he gives him another football and charges at him again.
After this, Bowser walks by the playroom and hears Bowser Junior and Joseph talk about blaming Chef Pee Pee is a good idea and he throws another football at them and charges at them, and he beats up Junior and Joseph as they lie on the ground helplessly for blaming Chef Pee Pee for the whole mess.
We then cut to the door where someone or something is trying to get out. We then see a hand unlock the door before we smash cut to black, and we hear Brooklyn T. Guy saying, "I told you not to open that!"
- Bowser Junior
- Chef Pee Pee
- Mebo (cameo)
- Terrance (background)
- Mario (toy only)
- Brooklyn T. Guy (voice only post-video)
- This is the first time that Bowser beats Joseph, most likely because Joseph was the one who suggested that Bowser Junior blames it on Chef Pee Pee.
- Joseph did a similar thing in Bowser Junior's Clown Car, where he wants Junior to shoot the cannonball
- This is the second video in this house where a couch is made dirty, after The Couch!
- The character painting of Chilly and her parents from the Buying Parents New Car vlog could be seen in the background in the living room.
- After the SML Question, there is a scene foreshadowing The Secret Door!.
- Logan and Lovell were the only two voice actors in the video (not counting Chris Pablo as Brooklyn T Guy since that is actually part of the next video).
- This is the first time in a really long time that Cody wasn't in a video with Junior and Joseph.
- At 8:40 you can see the words spell out May 10 on the Magnetic Whiteboard.
- This is the last SML Movie before The Secret Door!.
- If Chef Pee Pee makes 25 cents a week, that means he makes $37 a year, meaning Bowser pays him much under the minimum wage, making less than a cent an hour.
- If Junior drank the Hawaiian Punch before making the dunk off the balcony, or if he moved it somewhere else far from the hoop, then the whole episode wouldn't have happened.
- This is the first video in a while where Bowser Junior tortures Chef Pee Pee.
- This makes a return of the classic SML episodes where Bowser Junior, Chef Pee Pee, and Bowser star the episode. Bowser watches Charleyyy and only Joseph plays with Junior without Cody.
- When Bowser beats up Junior and Joseph, you can see Mebo and a Mario toy.
- In the behind the scenes video, it is revealed that when Lovell was smearing lasagna on Bowser's bed, some flew on Junior's face.
