What has been the most unexplainable python to hatch from one of your clutches?

Has anyone had any clutches that has delivered a unexplainable snake?

Such as a trait/morph that was highly unlikely or even completely unbelievable to have came from your breeding pair.

Or whatever, just unexpected.

Also have a beautiful day.

I have had a few non textbook mutation, in other words looking very differently than similar mutations with identical genes, and also some crazy extreme ringer + paradox animals, but nothing like bonus genes or things of the sort but it happens simply because some genes are subtle and get lost in some combos making them hard to identify.
