SMG4: Mario's Bus Trip is the fourth episode of Season 12 and the six hundred and seventy-fourth overall to be uploaded by SMG4.
Mario and friends go on a bus trip but fate (and marios 'specialness') has a different plan for them.
The gang, led by Shroomy, go for a field trip into a forest in Rockford, with Swag as the bus driver. As the bus departs, Mario suddenly felt the urge to pee, but Saiko was there to babysit him and make sure he couldn't get into trouble. Meanwhile, Boopkins was left behind, and grabbed hold onto the bus bumper.
During the trip, Melony was still pestered by the bully, Saiko is trying her best to keep Mario out of trouble, while Boopkins managed to get to the bus' side, and Bob, who was too influenced by playing Grand Theft Auto Online, thought Boopkins was a gremlin and tried to hold him off. As the they drive deeper, Shroomy notices a bear, and remembering what happened about a month ago, orders Swag to ram the bear as revenge.
As Boopkins and Bob hang for dear life, Melony sees them and tries to help them while on the bully's advice to use her deity powers, tried, but failed, and both were sent tumbling down the road. Mario convinces Tari to release him from his shackles and ordered Swag to stop the bus, only for him to crash it instead. Mario did eventually urinate, but was tied to the roof of the bus to prevent any more trouble. As they were about to head deeper into the forest, Shroomy notices a bear standing in their way.
The bear was apparently angry at the bus for what Shroomy did earlier, so it called its gang to beat them up. Shroomy, ecstatic for revenge, fought back, but was easily overpowered as well as the rest of the gang. Melony, watching the crisis unfold, took the bully's advice (who was resting) to focus her deity powers and defeated the bear gang, but went overkill and passed out at the end. When Melony regained consciousness, she saw that her friends were safe as they were driving. The bully told her that they were safe thanks to her, but then told her that she went into overkill mode, but overall saw good heart in her. The bully, introduced himself as Niles, said he wanted to help her master her deity powers, and Melony agreed. As they shake hands, she gets electrocuted, and Niles gave her the first lesson to expect the unexpected, explaining why he was pestering her the whole time.
As the bus leaves, Saiko and Tari realized that they forget Mario. Meanwhile, Mario was kidnapped by Gummy Bears to be tortured.

- Before, after Mario screams in horror as the Gummi Bears begin which immediately transitions to Anti-Shroomy saying "Yes!". This was later changed hours after the blooper's release to simply end with Mario screaming.

- This blooper reveals the name of Bully, Niles.
- This is Saiko and Tari's first appearance in Season 12, as well as finally marking their returns of them since SMG4 Christmas Special 2021, over a month since.
- So far, this is Tari's longest streak of absences at the start of a season with 3 episodes before returning in the fourth episode.
- This is the first school/college-themed episode where Melony is in her normal clothes and Meggy does not appear.

- This is, once again, the second episode in a row.
- This is also the twelfth type to focus on the original characters.
- This is the second episode Swag is in where he is uncharacteristically scared to fight.
- The episode marks the return of the Mario's Trip miniseries since it's discontinuation in SMG4: Mario's Train Trip from 2017. however SMG4 and Toad are absent.
- The way how Saiko tries to keep Mario from causing any trouble on the bus is similar to how she tried to keep him & Meggy from fighting over a chocolate bar by keeping them in timeout in SMG4: Doomsday but Mario is Okay. Which ends up by Mario causing destruction to distract her & the others.
- This is the first video since SMG4 Christmas Special 2021 to use the current logo, and the first episode of Season 12 to use it.
- Like the aforementioned blooper, this shares an eerily similar thumbnail, although with Meggy and Luigi's absence from it.
- Luigi, Meggy and SMG4 are the only main characters to be absent from this episode.
- The fourth wall is broken by a text reading "A couple of episodes ago..." during the flashback to "Mario Waits For The Bus" to reference how many episodes have passed since Shroomy's previous appearance.
- The footage used at 2:50 on Bob's switch is from the Youtuber Smii7y's modded GTA video.
