Lost green tree frog about palm-sized near Lake Champlain in the Plattsburgh-Adirondacks area.

I lost my beloved green tree frog, which is about the size of my palm, while hiking near Lake Champlain in the Plattsburgh-Adirondacks area. I think it may have hopped away while I was taking a break by the water. It's very lively and friendly, and I'm really hoping to find it soon as it's been a part of my family for quite some time.
