Looks like a cool aberrant pattern to me...
That stuff happens even in normal snakes. I have a female that has numbers on her side, one that has a snake on her back, and I just hatched one with a key on its neck...
With something like that you need more than just one example for it to be considered something other than just a cool pattern on that particular snake.
Cool pattern, though!
