Noggin

Noggin - a squat, stone-bodied elemental creature, no taller than a halfling child, with a rounded, drum-like torso that resonates when struck. Its most striking feature is its broad, flat head, which it instinctively taps with its stone knuckles to create rhythmic percussive sounds. Its arms and legs are short but sturdy, ending in three-fingered extremities resembling crude, humanoid hands. Its eyes glow with a soft blue luminescence, like gems lit from within, and its rocky skin is cracked in places, suggesting it was hewn from some ancient cavern wall. Noggin carries an air of innocent curiosity; it sits with its legs outstretched, tapping on its hollow body, producing echoes that ripple like faint drumbeats across stone corridors.
