What should/can I make?

[AaronP]

I would do this:

Black Pastel x Normal Female - Statistically 50% Black P. & Normals
Black Pastel x Normal Female - Statistically 50% Black P. & Normals
Black Pastel x Pinstripe - Black Pastel + Pin Morph (IDK What it'd be called) & Black Pastels & Pinstripes & Normals
Pied x Spider - 100% Het Pied Spiders & 100% Het Pied Normals (With this one you keep the females to breed back to their father)

With your black pastel you can sell the male offspring and keep the females to breed back to daddy for some Supers!
