The cow exists, the Panda Pied is created by a mixture of Pied and Super Black Pastel.

Where is this blue hypo you speak of? As far as I know, there are no alleles in a ball python for the blue coloration.
There is a red ball python though, I think it's referred to as the infrared or something?
The problem with Halloween is getting those genes to work out. Black pastel with something like a YBxHypo cross may end up with an orange and black snake.
