Pillow Dragons are covered in enormous amounts of fur affectionately referred to as fluff. Despite their deceivingly large size, they can still fly even with such tiny wings because their bodies are remarkably light. Pillow Dragons have a habit of sleeping for up to eighteen hours a day, waking only in short bursts. During their few waking hours, they take the time to hunt for prey. Once a pillow dragon becomes an adult, its fur grows very slowly. Pillow dragon fur is used to make very expensive and valuable cloth known as “dragon cashmere.”

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Just like his owner's other Pillow dragon, Totoro Demon, Totoro In Between is often accused of being Totoro Angel and gets stuck with little ones of other dragons. He doesn't mind them, but he is just not the babysitting type and always does something wrong like forgets to feed them. He would sometimes return after hunting food for himself and finds hatchlings waiting for him with hungry looks. At least In Between doesn't eat the food the moment he catches it and has plenty for all hatchlings. Sadly, not for himself.
