Golden-brown Syrian hamster with white belly

I lost my golden-brown Syrian hamster yesterday around 3pm near the Joplin Public Library on Main Street. It's a tiny guy, about the size of a ping-pong ball, with fluffy golden fur, a white belly, and a small white patch on his chest. He has a slightly lighter left ear and a tiny scar on his right hind paw from a little tumble last week. He was in a blue travel cage, but he slipped out while I was packing up a snack for our walk. My daughter adores him; he's really special to us, and I'd be grateful for any help finding him.
