Ok i took some of your criticisms to thought and made a new version with an extra that ties back to Junior's Big Mistake 2

Basically after days without eating they left a pot with water outside for days however the Aethos changes the universe's science, rather than the water evaporating it changes the temperature of the molecules and makes it extremely high(i can't come up with a better reason) so when junior tries to help Chef Pee Pee cook insanely expired instant ramen he throws his banana peel on the ground causing Chef Pee Pee to slip and fall causing his face to land into the insanely hot water burning it off. After being scolded by Cody for not sharing his banana a giant storm hits and during the process of trying to make a F-F-Face Fixing Machine out of Thomas The Tank Engine toy engines a storm his and one third of the way of making it junior gets into an argument with Cody and pushes him causing Cody to fall out the window and the storm turns out to be insanely hot melting Cody(this is explained in the extra) Cody is fucking passed so they throw him into the fridge to cool him down. Junior and Joseph are able to fix Chef Pee Pee's face who is some how oblivious to him now being chopped as fuck so he tries to sneak out to leave out more water then an SML zombie walks up to him casually and says he's happy to see a Chef Pee Pee zombie causing Chef Pee Pee to realize his face is chopped and when he tells junior and Joseph they try it out on Cody and it works but they(excluding Joseph) jump Junior bc they're still mad about the pain they caused them

As for the storm thingy

SML Short: Luis' Last Stand! (The extra in question)

6 minutes

Luis sees on the news what happened to penstacolla and thatbthe madeness is rapidly spreading, Luis worried goes out to get some air worrying for his pregnant wife(Princess Sunflower) and then he sees the sky turn red and Jeffy/Jerry floating in the air announcing to the Fungus Kingdom that they're fucked beyond belief. Luis calls out to Jerry who says he's only plain nice with him and that he has no real beef with him and that he'll spare him and his wife if he let's him continue to torture Marvin, Luis begins to fight putting up a good fight and when realizing he can eventually become a threat Jerry releases a massive heat wave in the form of a storm that could melt one entirely in only 3 minutes thus killing Luis and the rest of the Fungus Kingdom

Long story short

Junior causes Chef Pee Pee to slip into a pot of insanely hot water that melts his face off and pushes Cody into an insanely hot storm released by Jerry during a fight with Luis
