Hornosaur
Hornosaur is a graceful, long-legged creature that resembles an Earth horse, except that it has a horn on its forehead and wings.
Its long tail streams behind it like a waterfall. The wings are easy to miss at first—they are thin, almost transparent, with delicate patterns. The horn is sharp and long, and despite their beauty, hornosaurs can be dangerous: they fiercely protect themselves and their young.
Baby hornosaurs are adorable: small, round and unsteady on their legs, they love tumbling in the grass and playfully butting heads. Their little horns are short and blunt, so it tickles rather than hurts. Their short, fluffy tails point in every direction, and their wings resemble butterfly wings. They cannot fly yet; the wings simply help keep them upright as they learn to walk and stumble about. As they grow, their bodies become taller and more slender, their wings larger and stronger, their horns sharp and long, and their tails broad enough to wrap around themselves while they sleep.
