huggy wuggy fnf stands 17 feet tall and is coated in thick, vivid blue fur. His limbs and legs are many feet long, with enormous yellow hands and feet at the end. The hands have enormous Velcro straps on them, and the feet have four digits, including thumbs, but they are fused together and cannot move apart (with the exception of the thumbs).

In compared to his long limbs, his torso is hefty and disproportionately small. His head is huge, with two very large black dilated eyes, giving him a disturbed and unsettling appearance; it appears that behind his plastic "eyes" lie gigantic shot, human-like eyes. His lips are enormous, bright red, cartoonish, and he has sharp jagged teeth. A closer look at Huggy's mouth reveals a secondary set of jaws at his throat, similar to the sharp teeth of a Moray Eel.

Huggy walks with a stiff, yet light and weirdly organic-looking gait. He is capable of breaking into amazing bursts of speed, propelling himself forward with his long arms and legs.
