SMG4: If Mario was in... Deltarune

Synopsis
Mario finds him in the world of Deltarune (or Undertale 2) See you all in 2019!

Plot
The video starts off with Luke Lerdwichagul and Kevin Lerdwichagul...

The actual episode starts off with Mario driving in his go-kart. In the process he runs over a stop sign, a man, and a taxi cab before noticing that he is heading straight into a barricaded tunnel. He makes a quick turn right, leading him onto a rural, unpaved road. This unfortunately leads to a steep cliff, causing Mario and his kart to fall into another tunnel that brings him into Hometown from Deltarune.

In Hometown, Mario starts causing all sorts of chaos on his kart by running over some citizens, hitting a car, and even stealing a donut from Undyne (who was dressed as a police officer), resulting in her and the police chasing him to a school. Realizing that he's now on the run, Mario breaks into the school before Undyne could find him near his kart.

After entering the school, Mario decides to look for a way to escape Undyne but is forced to go the other way after seeing Baldi in the hallway. He enters a classroom and is subsequently accepted as a "foreign exchange student" by the teacher, shortly before Susie storms into the room "on time for once." However, Mario then proceeds to insult Susie by calling her "Barney" (a reference to Barney the dinosaur), leading to him being sent out of the classroom so he can apologize to Susie. In the hallway, Susie is about to beat Mario up but he manages to run away, even when Undyne had entered the school to give Mario payback for stealing her donut.

Eventually, Mario and Susie both enter a dark room where the door closes behind them. They both fall into a strange area where Mario plays with one of the local "objects," prior to stumbling upon a castle with some sort of fountain coming out of it (which Mario claims it's made of Pepsi).

As Mario exits the school, he realized he's being surrounded by Undyne and the military.
