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! As a truly wild Kuroba, these Fire Kuro are almost impossible to contain! With the power to throw flaming lava balls and a destructive personality, these dangerous Kuroba are a tough match, but if bested in battle, Lavapop will prove to be a most loyal Kuroba friend! When in battle, they ignite and become huge balls of flame - but retain their shape and color (think marshmellow puff size!). They also can leave tiny flaming coals behind them when being chased.
