Expect a frosty welcome from the Ice Rat in its BattleCave! It bares its needle-sharp teeth and looks menacing with a spiky crest of ice crystals on its back. Those who still dare to approach must be careful: A dangerous ice slingshot is circling above the BattleCave. Watch out! Can be stacked and placed with other BattleCaves to form large fortresses. Each wall can be individually replaced, to reconfigure the cube. In the last second, the pointed shards of ice spring up to pierce any enemies! The links of the ice slingshot can be individually extended or joined together to form a chain.
