How to produce a Silver Bullet and Super Pewter?

Pastel x Super Cinny = Silver Bullet (is it that simple?)

Super Pastel x Super Cinny = Super Pewter (also that easy?)

well a silver bullet is a Pastel/Super Cinny, you do not breed a super cinny to a pastel, that could only get you pewters, you atleast need more snakes to have a cinny gene and one to have a pastel to even have a chance of making silver bullets, like pewter x cinny.

same with a super pewter, they are super pastel/super cinny, so at the very least you need a pewter x pewter breeding.
