Thumbelina, a five-year-old miniature horse, is listed at 17.5 inches tall and just 57 pounds. According to the Guinness Book of World Records, this makes her the planet's tiniest equine.

She will make her first-ever public appearance in Canada as part of the Canadian Pacing Derby program. Thumbelina was slated to arrive in Ontario on Wednesday and to visit Toronto's Sick Kids Hospital on Thursday. On Friday morning (August 15), she will guest on Hamilton's CH Morning Live and on Sunday, she will be at Woodbine to visit fans in the Family Fun area.

Thumbelina's Children's Tour, in which she travels in her very own RV, has raised more than $1 million for children's charities across North America. To find out more about Thumbelina, visit www.worldssmallesthorse.com.
