Oh god. Now that I'm looking at the head pattern it is absolutely a rainbow boa of some sort. I'm also guessing Colombian, it is in pretty deep shed but there is absolutely no red pigmentation and as Tikall said the patterning suggests more Colombian than Brazilian.

I can't believe I slipped up this bad and thought that it was an aussie python, that's a hell of a mistake on my part, but also for the vendor who was completely off base advertising (and pricing it) as a Childrens. Time to contact the vendor.
