I know the "points" come in darker as they age ... maybe he's just a reallllllly slow chameleon, like we tease Miss Hoppy. When we got her, she was all one color brown, then she got a small dark spot on her nose - Paul thought she had hurt herself, but nope! You've seen her now with her dark ears and feet, and she's got subtle patterns in the browns that change over time - as does the shape of the dark area on her nose!

Maybe Sky'll keep you guessing as well.
