Yellow Bellies resemble dodo birds to a degree, being portly, feathered creatures with large beaks and short legs. They come in many different colors, and are notable for their long, pennaceous feathers extending from their heads and tails.
The term "Yellow Belly" derives from the very large, colorful stomach of known individuals. It is unknown why the creatures have such a feature, though it may play a part in mating rituals.
Though biological relatives of Sharpteeth, Yellow Bellies are nowhere near as cunning or vicious as their cousins. They are very laid-back in terms of lifestyle, usually spending their days gorging themselves with berries, which are considered a delicacy by the creatures.
When not eating, they can often be seen dancing and singing, or sticking their rear ends in the air in attempt to hide from predators.
