Pantomime horse

A pantomime horse is like a big silly costume that two people wear together to pretend to be one animal. Imagine if you and a friend stood on top of each other and put on a big costume that looked like a horse. You would be the front legs and head of the horse, and your friend would be the back legs and tail. When you moved together, it would look like you were one big silly horse! Sometimes people wear pantomime horse costumes to act in plays or put on shows. It's like they're pretending to be a real horse, but making people laugh at the same time because it looks so silly.
