Lost green tree frog named 'Bubbles' with yellow spots near a pond in Northern Michigan.

I lost my green tree frog named 'Bubbles' while I was hiking near the pond in Northern Michigan. I've had Bubbles for about two years, and he's bright green with little yellow spots and a slightly lighter belly. He hopped off my shoulder when I was trying to take a quick photo of a sunset. I've been looking for him all evening but couldn't find him. Any help would be appreciated!
