Arwolder is the first evolution of the starter Pokémon, Calignus.
Arwolder is a large and furry cow-like Pokémon. It has a dark brown coat and a light red underbelly. Its hooves are large and light gray. Arwolder also has red eyes and two pairs of red horns, the second set being larger than the first.
As its internal temperature rises, its thick coat begins to singe and fall off. This often creates scented smoke trails that can be seen from great distances. At night, a herd of Arwolder mimic a starry sky.
Its smoking coat gives off a fragrance that smells like what it has just eaten. When it sheds its coat, Trainers will often gather it to sell. At night, a herd of Arwolder mimic a starry sky.
In ancient times, evening travelers would mistake herds of Arwolder for stars, following them for miles.
