C Klanger Elements: Clockwork Recipe: x4 Copper x4 Spring Nebulox Crystal x4 Stone Bio: Klanger is a monster which seems to be completely made up of springs and metal. Like a clock, it contains a mainspring in the back of its head, producing a constant supply of energy. But, what makes it different from an ordinary robot is that its mainspring is recharged by a nebulox crystal in the core of its body. The crystal also allows the Klanger to power certain parts of its body, acting like a nervous system.
