Meanwhile, SMG4 using the Wing Cap was flying around Rainbow Ride until he crashes into a building falling into Peach's Castle, he's heading back to his room seeing Mario watching machinist SM64 bloopers until he realizes Mario's watching a video which presumably seems to be made by SMG4. They quickly notice the author of the video was SMG3. They try to call the police, but to no avail. They send an e-mail to YouTube but failed. They got a note from MCGustavo who helps them find SMG3.

Upon hearing this, FightingMario54321 arrives to beat him up. The gang cheers for FM as SMG3 jeers at the gang.

- At 2:39, SMG4's text is red instead of blue.
- The part where Mario calls SMG3 a boob guy is a reference to How Mario was Born due to the fact that the boss called Baby Mario boob guy.
- X's ripoff in SMG3's video is called Y. This is a way to mock the alphabetical letter as a simple name.
- This episode depicts SMG3 as a ordinary guy who ripped off SMG4's name and color code in an attempt to be more popular. SMG4: Mario's Spicy Day 🔥 and SMG4: SMG4's Origins retcons this: the former episode shows that SMG3 stole SMG4's video ideas because he was jealous of his popularity in meme school and the latter episode reveals that he has always been SMG3 ever since birth.
- According to FM, this episode was actually multiple people coming up with ideas, X coming up with the dopple vid itself, FM coming in to save day, he does know that MCG did an idea for the episode but doesn't remember it. However, only X was the one that was credited for the idea of the episode.
