Lost bright green pet tree frog named Kiwi with golden spots near a stream in the High Rockies.

I recently lost my pet green tree frog, named Kiwi, while hiking in the High Rockies. I realized he was missing when we took a break by a stream and he might have hopped away while I wasn’t looking. He's about 4 inches long and has a bright green color with small golden spots. It's really important to me to get him back, so please let me know if anyone finds him!
