The Feathered Micro Dragon is a Kickstarter exclusive with an unknown element. It is currently the smallest known dragon, and the only dragon that is known to have feathers (although it has been hinted that there will be other feathered dragons).
Gameplay
This dragon will feed on abandoned/unguarded eggs, acting as "nature's cleanup-crew," and is the only threat to the otherwise invulnerable eggs. Female Micro Dragons can eat their own eggs to prevent starvation.
