Pink Dragons are primarily herbivores and only eat meat during the mating season, when mates will exchange kills. When it is not breeding season, pink dragons spend most of their time incubating eggs and caring for their clan’s young. Due to their feminine color, it was traditionally thought that pink dragons were a strictly female breed, but this is not true.

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.

Tough stuff was given his name shortly after his handler discovered what gender he was.

Initially his name was to be "Pink Petunia", but as that would be degrading to such a masculine male pink, it was thrown out the window.

His current name was chosen based on the fact that he likes to eat bark and metal scraps (Aka. Tough stuff) alongside the typical pink diet of vegetation.

He also teaches the other young males in the clan how to do the same, all the while telling them that this will make them look "tough and manly". Due to this he is very unpopular amongst the female dragons and mothers. He has had much difficulty finding a female that can tolerate him and his... habits.
