But I can tell you a spider is co-dominant, so to make them, you need to actually buy a spider and breed it to a normal or another spider or such. Here are some of the more common ones:
Spider + pastel= bumblebee
Pinstripe + pastel = lemonblast
pastel + bee = killer bee
leucistic = super form of mojave (mojave + mojave)
ivory = super form of yellowbelly (YB + YB)
Spider= codominant, must buy spider
pinstripe = codominant, must buy pinstripe
Piebald = recessive, breed two het pieds
