I know you're trying to "blend-in" widdle froggie, but it doesn't seem like you're fooling anyone into thinking you're a thorn. You're too round and squishy... Just sayin'.
This widdle guy is known as a Panther Chameleon, maybe because of his dark stripes? But I've also heard chameleons change their color to blend into their environment. So maybe this lizard has been hanging around too many wild cats?
