Gameplay for the new boss fight against Prince Mush in Paper Mario: The Thousand Year Door for the Nintendo Switch. He acts as the game's superboss in the Glitz Pit, being the hardest boss fight in the game.
Despite that, he isn't all that difficult, although you'll be forced to superguard to damage him once he charges up. The Prince Mush battle is exclusive to the Switch remake.
