I’m convinced that Mickey Mouse clubhouse is set in a post apocalyptic world where Mickey rules everything as a dictator. Think about it:

All tehnology, all buildings, all personal items are Mickey shaped.
The only people you see not in Mickey’s crew are usually from outer space.
Everyone is always chanting something strange, usually about or involving Mickey.
He knows everything that’s going to be useful later, meaning he probably set up the entire plot himself to keep his underlings loyalty to him and his “all knowing ways”

Mickey is a manipulative dictator. Don’t let him lie to you.
