'Banana Ktulu' ball python (oooh!). "The Ktulu gene is a co-dominant gene that is exclusive to us at Constrictors Unlimited. We have high hopes for using it as a new tool so we started by proving it genetic with the Banana Ball Python gene. I love this combination. The Ktulu brought out some nice burnt orange colors surround lavender spots on the back. The Ktulu also added some nice pink sides to the Banana Ball Python."
