They are intergrades between an albino Corn Snake and an emory's rat snake/common corn cross. These snakes bring out the yellow and downplay the reds of the Corn Snake. Most are varying shades of yellow with darker yellow to orangish blotches. Clutches are generally smaller in number but produce larger, more vigorous hatchlings. Creamsicle with less emory background and increased amelanistic corn generally have lighter backgrounds and red to orange saddles (red creamsicle).
Not sure what Jeff's ingredients are BUT they are stunning snakes!
