Lost bright green pet tree frog with small yellow spots near the riverbank in Gold Country, California.

I lost my pet green tree frog while hiking along the riverbank in Gold Country. I had taken him out for some fresh air and he jumped out of my hand. He’s about the size of a child’s palm and is bright green with small yellow spots. I’m really worried about him, as he’s been with me for quite a while and is not used to being outdoors. If anyone finds him, please reach out!
