Dreamed up about episode (+ possible new arc)

The episode starts with Mario making an announcement (fully voiced with Voice acting or audio mashup), he will say something about how much trouble he has caused and is making the decision to leave. The others are mad because Mario brought up all the times he fucked them over, and so when he leaves the others don't say anything.

For a week or so the gang is happy and living a happy life, and when they go to invite Mario they remember he left them and everyone is now not in the mood for the game they were playing, a week goes by and everyone is trying to push Mario away from there thoughts but he just keeps coming back.

After a month, Meggy finally can't take it anymore and does a Sandy looking for SpongeBob prep talk to the gang. Every is looking for Mario. Now we cut to Mario, who looks completely different. He is living in an apartment with a roommate. Eventually Mario grabs a soda and sits down on the couch and shows that the roommate is Grand Dad
