Dress up your favorite character and get ready to battle! You will have to do your best to win the battle. If not, you won't be able to unlock the outfits.

Go into the fancy arcade where there are a lot of sweet things such as candies and cakes. Turn the arcade into a battleground and kill your fellow players by blasting them off before they manage to escape.
