These large, flightless, bird-like aliens are quite docile. Puffkins can grow up to three and a half feet in height and use their hooked beaks to dig up roots and hunt for small prey.
They roam the wilds near the colony in small flocks carrying their young within their thick, almost fur-like feathers. Those dense feathers help protect them from predators—of which they have quite a lot. It seems that to humans and aliens alike, their eggs and meat are rather tasty.
