Instructions
Hold the body in one hand and grasp the key chain at its base where it meets the head. Tug on it until the head pops off.
Remove both the hands from the LEGO minifigure by pulling. The hands are the "U" shaped devices on the end of the arms, made for grasping certain LEGO accessories like a claw.
Grasp the legs in one hand and pull on the torso with the other to disassemble the two pieces.
Pull each leg and each arm off to complete the process.
