Gray dwarf hamster with white belly, lost in Mansfield

I lost my gray dwarf hamster yesterday around 3pm. It's about 2 inches long, with soft gray fur, a white belly, a tiny white patch on the right ear, and a faint cinnamon stripe along the back. Last I saw it, it disappeared toward the Mansfield Public Library on Park Street, near the cafe and the bus stop. It's really shy and I'm worried it might slip into a hedge or under a bench. My daughter adores him; this little guy is a birthday gift and means the world to us. If anyone finds him, please reach out; I'm really hoping for a safe return.
