Lost small vivid green pet green tree frog last seen by the rock garden in a backyard in San Angelo.

I lost my pet green tree frog while playing with him in my backyard in San Angelo. He usually loves to jump around by the rock garden, but I can't find him anywhere! He's small, about the size of a golf ball, and very vivid green. If you see him or have found him, please let me know. I'm really worried about him!
