Lost small bright green pet tree frog with yellow markings in a park in Richmond.

I lost my pet green tree frog while visiting the park in Richmond yesterday. He slipped out of my hands while I was trying to move him to a safer spot away from some kids playing with a ball. He's small, about the size of a ping pong ball, and has a bright green color with some subtle yellow markings on his back. I'm really worried about him, so please let me know if you spot him!
