For $50 you could get yourself a 1/4 scale Gollum / Smeagol replica figure. It’s fully articulated and features 25 points of articulation. It’s quite detailed with liver spots on skin, scrappy hair, wrinkles, rotting teeth, etc. The replica figure can balance in his signature crouch without falling and measures roughly 10″ (25 cm).
