Li'l Tot
White earth pony with dark pink mane and tail, blue and lavender doll, teddy and ball symbol
Although she looks a lot like she ought to be with the Birthflower Ponies, Li'l Tot is actually an offer pony in her own right. She has a connection to sick children, and, if I remember correctly, was offered as some kind of fundraising pony, with sick children also receiving a pony.
She was never sold in the UK, and was only issued via special offer in North America in the earlier years of the Mail Order system.
