Mugwah was the sire Stormy's last foal, 1978 chesntut pinto mare Foggy Mist. Foggy Mist was the result of an accidental breeding between the two. Very little is known about Mugwah but a picture of him has been uncovered and we now know that he was a solid bay.
Mugwah was likely the sire of others members of the 1978's Chincoteague Miniature Pony Farm foal crop: chestnut mare Gusty out of Misty II and bay mare Raindrop out of Rainy. It is also likely that he sired other foals at the Pony Farm.
