Black Tea Dragons have small scent glands on the underside of their wing arm that release a pleasant scent. Though many creatures enjoy being in the vicinity of Black Tea dragons, the scent is intended to draw in swarms of butterflies. Though Black Tea dragons are full sized dragons, these insects are the mainstay of their diet.

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.

Oolong doesn't do too much guarding of the Berry clan, but he is good at attracting small insects as prey for the munchkins. He tolerates their actions, allowing them to share in the bounty of insects and is generally patient with all of them except maybe the misfits.
