Hi, I am not sure he is a gray tree frog but It is my best bet. I found him injured outside my friends house. His leg seems to be broken or something. He can climb though, just not hop. I have absolutely no idea how to take care of him! He is a a container with a shallow plate of water, a fake plant, paper towls, and a hollowed hermit crab log. I just found him a few hours ago!! Please help me!! I live in Lincoln MA. Does anyone want him??
