Thumbelina is smaller than a decent dog. So small, in fact, that the Guinness folks — no, not those Guinness folks — recognize her as the smallest. From Boing Boing:
Thumbelina is the world’s smallest horse. She weighs 60lb and is five years old. She was born on a ranch that specializes in breeding miniature horses. She is thought to have dwarfism, which makes her even tinier.
But she’s not alone. The Burleson’s Black Beauty may be an awkward lap-horse, but she held the title for five years until Thumbelina undercut her by an inch in 2006. That made Cuddles angry, of course.
Two more things you didn’t know: The world’s largest rocking horse is much bigger than you think, and equestrians like to be on top.
