Unlike other Pied combos it seems that the Enchi gene does not allow the Piebald gene to dominate it. Instead of making the classic 90% white snake with an unusual head it appears that you can get pied markings mixed with Enchi color and markings.

As an example the Spider Pied, Sable Pied, Bumble Bee Pie and Desert combo Pied have all made 90% white snakes with the combo patterned head. Although nice, it seems to be a dead end if you plan on going further with it.

The Enchi stuff may keep that door open!
