This plastic/rubber pony ball (like a hop ball with a head) has been one of C's all-time favorite toys. When she was little she had the Rody (actually shaped like a horse). Rody is now K's horse. A few weeks ago, C accidentally popped Pony by hopping on a small toy. She was devastated. We ordered her a new one for her birthday but due to technical difficulties it has not be inflated yet.
I should take some pictures of C riding on it. She can fly around the room and navigate tight spaces like you wouldn't believe.
