Nightmare Fuel: The Grey Mouse's schemes. They are always a variation of "let's replace Mickey and make everyone believe he's the imposter, then kill him", and he's damn good at them-In the latest, one of the people he convinced he was the real deal and Mickey the imposter was Mickey Mouse himself.
So Bad, It's Good: The 2002 story Attack of the Killer Penguins. Mouseton gets attacked by giant fish, Mickey is turned into a penguin, grows ostrich legs, has to defend Mouseton against the titular giant penguins, grows giant ears and starts flying... it makes sense in context, sort of. Or not.
