SMG4: The Ultimate Gamer is a blooper uploaded on August 25th, 2018.
The episode starts with Mario and SMG4 standing outside the castle WOTFI style before charging at each other and switching to GMOD 2D ragdoll combat where SMG4 hands Mario's ass to him. Turns out they're both playing "Super Smash each other in the ass Bros". This marks the 20th time Mario tried and failed to beat SMG4, the latter calling him out. Mario says he's gonna train to become better than SMG4 and runs out.
Mario's idea of training however is eating ice cream at the mall. He hears some commotion and goes into a game store to find a crowd gathered around a TV screen. When Mario asks Fishy Boopkins what's going on, he says Bob challenged a girl to Super Smash each other in the ass Bros, and apparently this girl is one of the best players in the world. Bob calls her out on being a girl, but when the round starts she single handedly wombo combos Bob. The crowd cheers and she shyly leaves the store. Mario decides to follow her. She gets startled by Mario's ability to somehow appear behind the doorframe, his ability to poke his head out of the drink machine, and then Mario confronts her directly, asking her name. She says her name is Tari and Mario says he wants her to teach him how to not suck at video games. Tari is at first not confident enough but after having Mario begging on his knees, she reluctantly agrees.
They go to the arcade starting Mario's training by showing Tari what he can do. As it turns out, Mario's only tactic is button mashing. Tari takes Mario to a Whack-A-Luigi machine to teach Mario how to focus. Mario says he's already focused, but inside his mind it's clear that he's being brainderped by Baldi doing the Fortnite Dance. When trying to play the game, Mario goes super fast and unfocused, so Tari has to freeze him using Popo's "ice cream" and it turns out Mario won zero points. When Mario tries focusing he actually manages to get a score on the game and accidentally whacks Tari's head in the process.
Next up is the crane game, used to train coordination, accuracy, agility, and chronic gambling addiction for kids. Mario tries to grab a partly eaten slice of pizza, but has to remember to focus. He ends up grabbing Toad after jerking the joystick so hard the claw burst out of the machine and started pulling him in. Toad holds on to an arcade game for dear life and Tari says she needs to help him, "him" meaning Mario as she uses a second claw to pull in Toad.
Tari's final lesson is feeding ducks at a pond. The lesson is that you need to be calm before a match. Tari ends up getting her hand nommed by a duck and starts to freak out. Mario says it IS relaxing hearing Tari's screams of pain. Mario asks Tari to go with him but Tari says she has to feed the ducks. Mario thanks Tari for her help and runs off to beat SMG4. Tari reveals to the audience that she's afraid of meeting new people, and then has to deal with the ducks again.
Mario and SMG4 have another rematch. Mario does better than last time but SMG4 still has the upper hand. It has a "i must remember what my master taught me but it turns out my master is actually watching the fight and speaking to me so it's not my imagination" cliche, and then Mario manages to pull in a cliffside victory. Mario gloats to SMG4, who defeatedly leaves, finding Tari peeking from behind the door, and then Mario brings her in to celebrate. Tari invites SMG4 to a consolation battle, and the video ends with the three playing together on a couch.
