16. Shetland Pony
This is one angry, pregnant pony, and if I were you I would not mess with her. Ponies are notorious for having a Napolean complex, or should I say larger-than-life attitude problems. She’s probably so uncomfortable being so big she can’t wait until the due date! Ponies have a gestation period of almost 340 days–the long pregnancy may explain the look on her face.
