Maniac Mary hits the Met Gala! You read that right, the biggest celebrity event of the year just got crashed by the Maniac of New York in the worst assault on high art since...well, since the last Met Gala. It's gonna be a bloodbath, and that's before the violence-thirsty Maniac Mary Bros show up to join her! Gina and Zelda will have to move fast if they want to save anybody!
