Grindlewort is a diminutive figure who radiates a frenetic, joyful energy. His skin is the texture of fine parchment, deeply lined with laugh lines that seem to pulse with a faint, golden inner light. His most striking feature is his hair, a shock of vibrant emerald green that stands at odd angles as if perpetually charged with static electricity. He wears a pair of oversized brass goggles with multiple rotating lenses, one of which is always magnifying his left eye to a comical size. He moves with a springy, bouncing gait, and the air around him smells faintly of cedar wood, ozone, and peppermint. Curiously, while his right eye is a warm amber, his left eye is a swirling vortex of tiny, ticking gears that never stop moving.
