In this king of the hill style fight, only one can be the winner! The ring even doubles as a carrying case for your characters and nano®, so you can pack them up and battle anywhere you want. With so many kooky characters, the possibilities are endless! Settle the score of age-old battles, or come up with the craziest fights you can think of. You can even print a template from HEXBUG's website and create your very own Box Sumo character!
