Changing Chameleon

I chose a chameleon for my future creature. This lizard adopts a behavioral adaptation to cut grass and weave it and use it as a shade umbrella. The chameleon of the future will also have to grow a water bottle that will blend into its body. It will be so hot that the chameleon will have to carry water with it like a camel. I think chameleons will be good at changing because they are already used to changing their color.
