Where's The Frog? (Updated)

Hat tip: Muqata

I don't know the story behind this picture, or whether it's authentic or not, but obviously my High School teacher was right when he told us about how well frogs can camouflage themselves to blend in with their environment when they are in danger--or in any sort of...pickle.

UPDATE: Thanks to Elder of Ziyon who found the source--and a picture of the Mandarin Grove Tree Frog

Now theres a frog with 'appeal'.
