The Iceguin Ace, like its name states, is a medium sized penguin-like creature. Its overall design resembles an old-fashioned aviator.

It has red eyes without pupils and aqua-colored flippers and beak, and on the top of its head are two stubby protrusions resembling thick aviator goggles, colored orange along the lengths and aqua at the ends. A ring of dark pink orbs around its neck resembles a thick insulated scarf, and colorful feathers hang down from the undersides of its wings. On the Iceguin Ace's belly is the Nightmare Dream Eater symbol.
