Every now and then out of the blue he puts on quite a show.
He is usually a brownish orange on his head, legs and tail with medium blue bars on bright green over the torso. I have seen him nearly all orange with yellowish orange stripes and some outrageously vivid combinations (like when he decided to bite the vet, hehe), most of which only last a few seconds.
Just when I think i have seen his entire repertoire, he throws something new at me. He is an amazing little critter.
