Lost small green tree frog named Hopper near the beach area in Gulfport, Mississippi.

I lost my green tree frog, named Hopper, while we were visiting the beach area in Gulfport. He got away when I was setting up our picnic. He is very small, about the size of a half-dollar, and really loved to hop around. If anyone has seen him or found a little green frog hopping about, please let me know! I'm really worried about him.
