Test the robotic rabbit in Usarobo Crystal. Outwardly, he looks like a harmless toy, but he is not at all unarmed. The rabbit can release large crystal hearts, enough to counter the glass monsters that will soon appear and try to intercept the rabbit. Collect crystal balls with carrots inside and coins to increase your score. Help the rabbit survive in a hostile world in Usarobo Crystal. At the end of each level, the hero faces a boss battle.
