Compared to Waddle Dees, Key Dees have distinctive red swirls on their cheeks and a stubby tail, both of which are unique to Key Dees. They have black blotches for eyes too, rather than the big, round ones that Waddle Dees have. Their color scheme is also unusual for Waddle Dees, as they have yellow bodies, pink faces, and their hands and feet are brown. All this makes them resemble a generic monkey more than Waddle Dees.
