Margaret

Margaret is a sheep appearing in the How to Train Your Dragon: The Hidden World extra feature, The Dragon Sheep Chronicles.

Dealing with Dragons
After Hiccup Haddock integrated the dragons on Berk, he continued to bring in more and more, especially after the events of the war with Drago Bludvist. As potential prey or playthings for these fearsome predators, Margaret the sheep details the various plans the sheep of Berk made to escape the island. Unfortunately each attempt was unsuccessful. Ultimately the sheep, assisted by Hiccup, lived with the dragons by wearing dragon costumes.

Physical Appearance
A number of sheep appear in The Dragon Sheep Chronicles, all of which were white. It is assumed that Margaret is a standard white-wooled sheep with a black or gray face and legs.
