Even though this is parody, I like that you clearly shown King Boo's life within the canon Nintendo universe.
King Boo is a suburban ghost guy who wants to hang with his ghost buddies and drink beer all day in the alley. However, he has these stupid, autistic brothers named Mario and Luigi constantly harass him as you've shown around the 9 second mark.
King Boo also has a stupid wife who constantly disturbs his peaceful time away from work to do some stupid shit like take out the garbage. King Boo isn't the kind of guy who would tell his wife to fuck off or that he'll do it later; he is a ghost of action, so he takes care of the garbage right at that moment; however, his ghost friends leave since the fucking wife ruined the goddamn mood.
Despite King Boo's reputation as a villain, you've have rightly shown him to be a super-chill ghost dude who has done nothing wrong, and all he wants in the afterlife is to not get hassled by his fucking ghost-wife or some retarded brothers, and drink some beer with his friends.
