Lost vibrant green pet tree frog approximately 3 inches long near Snake River, Wyoming.

I lost my pet green tree frog while camping near the Snake River in Wyoming. I had him in a small container, but he managed to escape during the night. He's about 3 inches long, vibrant green with some light yellow markings. I'm really worried about him, especially since we are in a wooded area with predators. If anyone finds him, please let me know. I'll be super grateful!
