He tells you himself in clutch 84...

Look at mom shes a desert

Ever seen a desert clown now add super desert. And yes there still could be a super desert its not proven dom or co dom yet. Just because a super hasnt been proven yet...doesnt mean it cant make a super.

Pesonally i think a super desert would be an all orange/gold snake but since mom is a desert, it must be included in the genes.

Enchi clown would have purple in it, he already made a lesser/pos enchi clown, looks nothing like the flatline. Enchi is not in mom or dads genes.

Like Ralph says its all in his birthing records.
