SMG4: Mario and The Diss Track

SMG4: Mario and The Diss Track is a blooper released on December 15th 2018.

Synopsis
Bob has officially gone too far... Saiko and the SMG4 crew prepare the ultimate diss track to stop him once and for all...

Plot
The episode starts off with the Mario Brothers getting kicked out of a restaurant after Mario was caught playing with the food. As Luigi starts lecturing Mario for his disgusting behavior, they notice that Bob has become immensely famous, and there's now shirts, balloons, and posters bearing Bob's name. Deducing how bad this will go, Luigi decides to go to the castle, but not before Mario steals another guy's balloon and floats away until he hits an airplane (which advertises Bob).

Meanwhile, Bob is at a huge mansion thanks to his overwhelming popularity with Fishy Boopkins' girlfriend, Saiko Bichitaru as his manager. He is annoyed at how his follower count hasn't risen up in days, and Saiko reveals that the reason was because everyone in the Mushroom Kingdom became his follower. The Garo doesn't care and explains that he wants everyone in the world to know his name. Saiko suggests threatening them, but Bob says it wasn't his idea but nevertheless accepts.

At Peach's castle, everyone is doing their usual hobbies, until Luigi bursts from the door carrying awful news. Toad happily asks if Mario died, only for the latter to show up carrying Bob's stuff, much to his frustration. Luigi explains that Bob has skyrocketed to fame, but the others think he's just jealous of the Garo, so they decide to watch one of his concerts on TV.

However, Luigi's fears are confirmed when the concert, called the "Ultimate Diss Track", shows nothing more than Bob hurling hurtful insults at his former friends, claiming they made his life miserable, and ends the rap by lying that it's all true. Mario isn't concerned at first, happy that they're at least on TV, but the others (especially Boopkins) are deeply offended and angry at Bob for humiliating them. Luigi then decides to tell the gang all about it.

Meanwhile, Bob is at the studio where he made his concert and is happy at how popular it will become (saying it was worth it sacrificing his friendships). Saiko is happy, believing everything Bob said was just a joke (unaware that Bob meant it) and leaves the studio, planning to start her own singing career. While exiting, she finds a Mario-esque shadow, and panicking throws her phone at it, discovering it was just Luigi. He reveals to Saiko that Bob indeed hated them and manipulated her just to get more fame. She refuses to believe it at first, but Luigi shows her what happened to Fishy Boopkins, who is shaking uncontrollably in sadness, and is starting to lose his sanity after Bob insulted him. Seeing what Bob did to her former boyfriend, Saiko agrees to join Luigi.

Back at the castle, the gang are formulating a plan to get revenge on Bob. Mario suggests slugging him with a baseball bat which Toad agrees on while Tari suggests a less-violent idea involving them challenging Bob to a video game competition. However, Mario and Toad instead laugh at her idea. Luigi then comes back with Saiko, who is angry at Bob manipulating her and for what she did to Boopkins, which relieves him. She suggests an idea in order to teach Bob a lesson he won't forget.

Back at his mansion, Bob looks on TV to see any possible rival, and discovers a rap called "Darkest Hour", where Saiko is the singer, Mario is the drummer, SMG4 and Meggy are the guitarists, and Luigi, Tari, Bowser, Boopkins, and Toad help film and record the rap. Their song did so good that Bob loses his fame and all of his fans to Saiko, plus they ditch their Bob Merch and refuse to listen to his raps (with the chef that kicked the Mario Brothers out of his restaurant yelling at Bob to stop). To make things worse, Bob loses his mansion, and though he tackles and defeats the Teletubbies responsible for getting rid of his house, another Teletubby grabs it with his bare hands and leaves with it, leaving Bob angry.

Realizing his fame and life had been destroyed beyond repair, Bob sees his friends inside a store and attempts to reconnect with them, only for them to shrug off and turn back on him. Bob then asks Fishy if he will at least be his friend again, but one look at Fishy's face was enough to tell Bob that his answer was no, leaving the Garo distraught.

In the credits, Saiko breaks the fourth wall by telling the viewers to check out her SoundCloud account.

Trivia

 * At the moment, it's not confirmed or denied if this episode is possibly the last episode of The Rapper Bob Arc.

 * At 9:59 Bob sounds like Darth Vader when a former fan drops his merch in the trash.
 * During Bob's Ultimate Diss Track, Luigi is doing the T-Pose, possibly in reference to SMG4: Mario And The T-Pose Virus.
