Short story behind him: his breed seems to be like a mini-Roadrunner but without the crest. This one, who we saw numerous times around the resort during our recent desert vacation, was moth-eaten, picked at, and generally kinda sad looking. We liked him, so we named him Mr. Scruffy (obvious name is obvious). He was pretty awesome and I miss him already.
And the methadone-induced weight loss didn't do any harm, either.
