Collectible Creatures with a Twist. Kuroba is a new way to play rock, paper, scissors! Select your play strategy and battle with your friends or train with your own practice cube! It is a well-known fact that you should never look a Frossmelt in the eyes, for when you do you are immediately frozen in place, which is not a state you want to be in when you find one charging toward you with it's icy cold horns. If you're planning on taking on this Ice Kuro, bring your ear muffs, and a Fire Kuro. Frossmelt charges in battle and uses it's horns to ram their opponents into submission. It can freeze any opponent. It can expand size in battle as it charges it's opponent, getting to size of an elephant.
