Rosebeasts are bulky, pink quadrupeds. Their heads, however, are normally red in color. The average rosebeast can grow to be up to twenty feet long, and nine feet tall. They have small, black eyes, and they are mostly blind. They mostly navigate by their senses of smell and hearing.
Rosebeasts survive on a diet of Tethys's Fern Forests. They also eat some other plants on their homeworld.
Rosebeasts live in small herds often involving five or six individuals. Their does not seem to be any genuine social structure whatsoever.
