Faery Dragon/Fey Dragon/Fairy Dragon/Penny Dragon
The Faery Dragon is a creature commonly from South American folklore. They resemble the typical European Dragon but range from the size of a mouse to a foot long. They also have two sets of wings resembling a dragonfly or butterfly, long tapered snouts, large iridescent eyes, and coloration matching their surroundings. Their scales are thought to reflect rainbows in the correct light.
