Kattis Dolls

The Barbie Riding Club was a series of dolls and horses, where most of the horses were interactive in some way. They could walk or bend their necks and make sounds. Kelly/Shelly had at least five ponies, of which three were sold separately.
The Shelly & Pony Gift Set was called Kelly & Baby Pony in the US. "Shelly saddles up for her first riding lesson at the Barbie Riding Club".
The doll is the same we got in a big single box in Europe, dressed in her gold trimmed, blue velvet vest and khaki riding pants, that matches her big sister Horse Riding Barbie's outfit. The pants have velcro on the bum so Shelly/Kelly can safely ride her pony and of course she wears a helmet. Shelly's pony walks and bends her neck to eat her carrots.
