Adventure Time Child's Deluxe Finn Costume, Medium

Your child never wants to be wandering around the Land of Ooo unprepared. Some of the precautions he can take to keep himself safe in that place are: having a magical dog named Jake as a best friend, learning cool ice ninja powers from one of the Ice King's tomes, or carrying around the Enchiridion with you. But the most important thing to remember when traveling across Ooo, is to dress just like Finn, in his totally mathematical Adventure Time gear, which includes a blue top and some blue shorts. It doesn't hinder movement like some of those clunky armor sets and it looks pretty rad when your kid is fighting the Lich while wearing it.
