Introduced in the 1980s and reintroduced in 2003, the My Little Pony line of mini-horses encourages children in traditional forms of doll play—fantasy, storytelling, hair grooming, and collecting. The small pastel ponies have come in more than 1,000 varieties, all with elongated tails and manes made to be brushed. The toys peaked in popularity between 1982 and 1993—even outselling Barbie for several years.
