Using this robot set is super easy! First, take out the 5 chibi robots from the package. You can play with them as individual animal - shaped robots. When you want to combine them, follow the connection points on each robot to build the 6.7 - foot robot. To activate the LED lights on the head, just bring the magnetic cat's paw close to the head. As for the weapons, simply attach the energy rifle and combat knife to the appropriate spots on the combined robot. When it comes to maintenance, keep the robots away from water and rough play. If they get dirty, use a dry cloth to gently wipe them. And store them in a cool, dry place when not in use. Also, be careful with the magnetic cat's paw to avoid losing it.
