If the Super Fire was carrying (and hiding under all that white) the additional gene that makes a heterozygous-Fire animal into a Striated.
Or, of course, the possibility of a mutation that's spontaneously cropped up.
The only way this would be possible is if the Striated gene wasn't allelic. From my understanding, you can't have something like a Super Mojave Phantom, because only two genes from that locus can be active in the same snake at once. You can't have an Ivory Super Stripe (in theory.) If the Striated gene isn't allelic though, it is totally possible that the Super Fire was carrying it.
I'm very interested in this Striated ball
