SMG4: Mario School Club is the second episode of Season 10 and the five hundred and fifty-third overall to be uploaded by SMG4.
Hal Monitor makes his debut. It was aired on January 25, 2020.
Mario and friends what to start a cool new club. But what will it be?
The video starts when Mario was shown on a stage with a fridge, hugging it. He then acted like the fridge was his friend and started crying. In the meantime, Luigi, SMG4, Bob, and the others were sitting and watching what Mario called a "club". Meggy Spletzer, on the other hand, called it a "Food Appreciation" club, and Luigi wanted his fridge back to eat dinner. Mario refused and resisted, but eventually threw it away. For Bob's turn, he showed his "Dumpster" club, representing it with a banana. SMG4 gave up and decided to leave the room.
Mario warned him that Hal Monitor was roaming around since they were actually trespassing the school, but SMG4 left anyway. Mr. Hall Monitor saw SMG4 trying to leave and started becoming pissed off due to knowing he was a trespasser, making the latter run back to the room in fear as the former approached him. Terrified, SMG4 asked what the guard even was, but Tari questioned Mario about why he wanted a club so badly in the first place. The latter then responded that it was mainly because somebody didn't invite him to a club. The plumber then decided to start a "Poetry" club, only for him to be interrupted by Meggy as she expressed her interest in helping him (provided that she and the others could decide what the club should be about).
The Karate Club
In this club, the gang watched as Meggy demonstrated how to beat a dummy (who later fell out and hit the Crazy Raisin Lady) using karate. However, when it was their turn to apply their karate skills, things didn't go like what Meggy was hoping for; SMG4 hurt his hand when he punched his dummy, while Luigi became scared as his dummy fell back on top of him. Fishy Boopkins apologized as he slapped his dummy to no avail, and Tari only hugged her dummy because of her pacifist nature. Axol tried to draw an anime character for karate purposes, but was stopped by Meggy because he shouldn't be relying on others to do his work for him. Shroomy fired some guns, but missed his dummy (narrowly missing Meggy in the process), and Bob cut his dummy in half due to having blades for hands. Finally, Mario used his backwards-long jump before launching himself outside when Meggy came, hitting the Crazy Raisin Lady a second time.
The Anime Club
Meggy freaked out about anime and its consequences due to the events of The Anime Arc, but was knocked aside by Fishy Boopkins. The Spike proceeds to show the club an anime DVD, whose translated title is "My Gym Teacher is a Sexy Rhinoceros." However, in the anime, the "teacher" simply chased and beat a couple of students in a burning school gymnasium, as other students panicked. Though Axol enjoyed what Boopkins was showing, the others didn't really like it. After Tari requested for him to show something else, Boopkins changed the anime to Pokémon, which was simply a low-quality version of the actual TV show, with MS Paint drawings of Jessie and James taking Pikachu from Ash (who let the Team Rocket members do so). Mario, finally fed up with all the terrible "anime", punched the monitor showing Pokémon, much to the delight of everyone except Boopkins and Axol.
The Computer Club
After SMG4 finished his instructions on making a computer, the gang attempted to create working computers themselves. Though Bob was frustrated over the fact that his computer was somehow a Mac, Boopkins was proud that his "sculpture" of computer parts is done. Meanwhile, Tari tested her computer by turning it on, but the computer somehow became Optimus Prime who then flew out of the classroom. Shroomy used a knife to sculpt his computer out of wood, and Meggy only used it as a "box" to hide in. Finally, Mario took a lot of random objects and tried to make a working computer out of them, but it ended up summoning a demon instead upon being turned on. Everyone started panicking as Mr. Hall Monitor heard their ruckus from outside, thinking that they were up to some illegal activity. They all stopped their chaos and pretended to teach math in order to reassure the guard that everything was fine, sparing them from getting in trouble at the school. The demon that Mario summoned claimed that he's seen enough shit and went back to the pits of Hell.
The Hunting Club
Shroomy instructed the gang as they prepared to shoot some animals, all while lying to Tari about the ability to hug with bullets, so she wouldn't consider the task to be "terrible" for their targets. Shroomy, in the style of the Sniper from Team Fortress 2, then drove an RV as Bob and Mario interrupted him, with the latter rubbing a gun against himself. The mushroom boy scout ordered everyone to focus as he shot some animals, causing a nervous Axol to write a note about "avoiding" his club leader in the future. Bob prepared to shoot, but on the order that any animal is a target (including those who behaved like humans), eventually firing his rounds at Axol (who is an Axolotl). Mario ate his gun, but got injuried form being internally shot (likely because he can't digest the gun), and Tari was shown chasing a zebra under the lie that she could use her gun to "hug" the animal. Luigi and Boopkins rode an elephant until their animal was shot down, while Meggy impressed Shroomy by not only shooting animals, but also breaking some of the plates on Don Resetti's "Plate and Pottery Store." Not wanting to "lose" to Meggy, the mushroom man started shooting at more targets aggressively, until he unexpectedly hits a Lynel hiding behind a bush. The Lynel was provoked by the bullet as Shroomy noticed that everyone had already fled the area, which led to the latter getting viciously attacked by the former.
The Board Game Club
Tari chose to play a game called "Ducks and Ladders" with the gang, which was basically "Snakes and Ladders" (or "Chutes and Ladders") but with "a pat on the back" replacing any negative consequences (or shortcuts from the ladders). However, Mario interrupted their "no risk" game by wanting to play "Call of Cthulu," which revealed a living tentacle once the box was opened. The tentacle grabbed Boopkins as Tari became worried about the Spike, but the others somehow became very interested in playing Mario's game.
The Mystery Club
As the gang was naturally confused over what to do in Bob's club, Boopkins volunteered to be the first to find out. Apparently, Bob gave him Pandora's Box and told him to open it. After opening it, the clip suddenly stopped and both Bob and SMG4 went to tell the audience that they had decided not to show what happened, and instead cut to the end where everyone was suffering.
They then tried a bunch of other clubs, but they sucked at all of them
As everyone was lying down in defeat, SMG4 said that all their ideas sucked while Meggy lamented for an idea everyone could enjoy. Just then, Axol suggested a Volleyball club, but Bob rejected it because he didn't want to do another sports club. Boopkins then suggested a friendship club, but Mario called the Spike gay because of that.
Just then, Tari had an idea. She whispered to SMG4 who declared that idea was the best.
The Lazy Club
Apparently, Tari's club idea was agreed upon by everyone to be the Lazy Club, where all they do is to sleep. Just as Bob cursed at Mr. Hall Monitor, he suddenly burst through Peach's Castle's doors, telling Bob that his comment was "not nice". The episode ends by everyone naturally screaming, as they were punished severely.
