The creator of the annual event, MC Ballyhoo and his sentient top hat Big Top organize the minigames played by participants of the game. Though the "MC" title often stands for "Master of Ceremonies", fitting with Ballyhoo's role in Mario Party 8, he claims that it instead means "Master of Catastrophes."
