SMG3 has gathered his team from SMG4: I Can't Believe It's Not SMG4! again, including Mario. This time, SMG3 has put together a plan to steal Susan's remote from her in order to rebuild his destroyed production studio. Will the heist succeed?
At SMG3's castle days prior, where the Anti-Cast is working on a plan to steal the YouTube Remote from the YouTube headquarters, with SMG3 planning to use it to rebuild his studio after it was destroyed by Isabelle and Sans as a result of SMG4's tampering. Although Mario was hesitant at first, SMG3 managed to get him into the plan when he reminded him of Greg's death at the hands of Susan Wojcicki.
Sometime later, the gang, mainly SMG3, Mario, and JubJub Boopkins managed to infiltrate into the remote room, and faced off Susan Wojcicki, who turned into a Barney-shaped creature who tortured the three. Although they managed to defeat her, they, along with the rest of the gang, was kicked out of the building after Susan used a banhammer on them.
They were all disappointed that it was all for nothing until Anti-Shroomy appeared with the remote. SMG3 revealed that he had a plan B in his pocket. Aware of Shroomy's past, he threw a demon mask to awaken his alter ego, therefore allowing him and his boy scouts to steal the remote while Susan was distracted. Now with the remote, SMG3 revealed his true plan: to destroy SMG4 once and for all, and delete him. Knowing that Mario would be a snitch, he betrayed him by summoning Oof Button to kidnap and send Mario to the Internet Graveyard to prevent that from happening, while the others look on at SMG3's descent into tyranny.
The scene changes to the present, where Mario is seen recapping the events, while SMG4's face had a nerved look, knowing that the SMG3 would totally do anything with it, confirming his rumors of his evil intentions, and decided to call the gang to stop Snitch Productions.

- SMG4: Stupid Mario Arcade: Prelude to this blooper.
- SMG4: The Internet Graveyard: This blooper explained how Mario ended up in the Internet Graveyard days prior to the episode, in which SMG3 decided to attempt to delete Luigi as well for him to have a little company.
- Susan Wojcicki's surname is referred as "Wojiski" by SMG3.
- This blooper takes place before the events of the previous blooper in which it was explained how Mario ended up in the Internet Graveyard.
- This marks the return of Kairi from Kingdom Hearts as the YouTube receptionist after SMG4: The Day SMG4 Posted Cringe, however this blooper changes her voice to adults in the Peanuts TV specials rather than Isabelle's.
- After the blooper was released, the channel banner was changed again, this time more glitches surround everyone except Mario, who now has a now confused face. Meanwhile, Shroomy's face is slowly fading away for his Demon Hunter alter ego, and SMG4 is darkened and the emblem on his cap changes to SMG3's emblem. His expression is also turning into a more sinister expression. Furthermore, the outline of Rob the Scarecrow can be found behind Bob Bobowski, Belle Fontiere's chest can be seen glitching in front of Tari's chest, Saiko Bichitaru has a blue patch of glitch on her eyes being similar to Whimpu's glasses, Meggy Spletzer has a green patch of glitch on her forehead similar to Melony's Watermelon appearance, and the Glitch Productions logo is slowly turning into the Snitch Productions logo. This likely foreshadows the official banner would replace SMG4's cast with SMG3's group.
- In the title and most of the dialogue, "YouTube" is mis-capitalized as "Youtube".
- This blooper's thumbnail references the "Piper Perri Surrounded" meme.
