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.
