Lost small bright green tree frog with yellow speckles near a backyard in Northwest Oklahoma.

I lost my pet green tree frog while taking it outside for some sunlight in my backyard near Northwest OK. It slipped out of my hands and hopped away before I could grab it. He’s pretty small, about the size of a quarter, and has a bright green color with some yellow speckles. I would really like to get him back, he’s very special to me!
