Lost small green tree frog named Hopper near the picnic area by the pond in the park in Tuscarawas Co.

I lost my pet green tree frog, named Hopper, while we were out for a walk in the nearby park in Tuscarawas Co. He likes to climb and is quite small, about the size of a baseball. He was last seen near the picnic area by the pond. I'm really worried and miss him a lot! If anyone finds him, please let me know!
