Henry offered to buy Misty, with the aim of using the foal as the model for her next pony book cover, but the Beebes refused.
[3] Misty was trained to both ride under saddle and to perform tricks, such as standing on a stool and "shaking hands", which she became famous for.
[8] A palomino pinto, Misty was heterozygous for the cream gene, which passed to only one of her foals: The Chincoteague Pony stallion Phantom Wings (1960–1964), who has no known descendants today.
Misty was also heterozygous for the pinto gene, which passed to her descendants through her third surviving foal, the Chincoteague Pony mare Stormy (1962–1993).
Stories announcing his birth appeared in numerous newspapers, and hundreds of people visited Beebe Ranch to see Misty's first foal.
Marguerite Henry also flew in to see the newborn; publisher Rand McNally sponsored a contest to name the foal, which was won by Carol and Cheryl Costello, a pair of twins from South Dakota.
Phantom Wings had a short career as a stud at Beebe Ranch, but only had one foal: A chestnut colt named Sandpiper (b.
Both Phantom Wings and Wisp O'Mist died from colic in December 1964, after breaking into a cow pen and eating too much feed.
[10] Misty's third and most famous foal was Stormy, a chestnut pinto filly born on 11 March 1962, during the Ash Wednesday Storm of 1962, a Category 4 nor'easter (tropical cyclone).
In 1967, at the age of 5, Stormy gave birth to her first foal: A palomino pinto named Thunder (28 May 1967 – 1986), sired by the buckskin Chincoteague Pony stallion Lightning, who had previously been bred to Wisp O'Mist.
Stormy passed away on 24 November 1993 at the age of 31 in Waynesboro, Pennsylvania due complications from an earlier surgery to remove a cancerous tumor.
