Duo's ears are his most iconic feature, but they're also the most challenging to turn in space. Dragging the top middle anchor point from side-to-side will give the illusion of a head turn. But don't slide it too far — it creates a unnatural pinch!
If you need him to, Duo can bend at the waist, elbow, and wrists. When bending at the waist, use a rounded rectangle to place over his body instead of editing his existing shape.
Duo's feet can separate from his body when he's in motion. They can also bend, lengthen, and even wiggle (like a hot dog). If Duo were to walk in the sand, his footprints would be perfect circles.
