And just so you know what you're talking about when you use those words, here are the definitions for each of them:
Zoeal: Any of the free-swimming larva of certain crustaceans, as the crab, having rudimentary legs and a spiny carapace.
Sajou: Same as Sapajou; a capuchin monkey.
Pyin: An albuminous constituent of pus.
If you don't, they are as follows: EAU, AA, AE, AI, OE, and OI
And if you completely bend the "sometimes 'Y'" rule and make it a 24/7 vowel (why not, right?), you've got even more to work with: AY, OY, YA, YE, YO, AYE, EYE, YAY, YEA, and YOU
