Brownies

Brownies are small easily angered but fearless creatures. They first appear in "Dragon Summit" and a Brownie individual called Reggie is featured in the "The Hunted" and Halloween Bash. All episodes taking place in Season 1. They are never seen or heard of in Season 2.

Brownies are usually ill-tempered and will tend to bite if threatened. This also applies when they're in a bad mood, and even when they're in a good mood.

Physical Appearance
Brownies are extremely small elf-like creatures, about no bigger than an adult fist. They have pointed ears similar to elves, and different shades of red hair depending on the individual. They wear tunics, pants, jackets and shoes made of cloth scraps and use ropes for their belts.

Powers and Abilities
Although Brownies do not actually possess magical abilites, they can be quite troublesome adversaries. Because of their small size, they can squeeze into tight spaces and can crawl under the clothes of someone caught unaware. They are especially hard to manage when they gang up on their enemies. However, Brownies are known for not being very smart and for their love of shiny things, which can make for a good distraction.

In "Dragon Summit", a trio of Brownies managed to single-handedly bind the American Dragon in a tight rope.
