If you mean what animals they're based on ill tell you!
Mary-Manta Ray
Crowven-Crow
Twyla-Owl
Reginald-Pufferfish
Vasilis-Deer (I think)
Ah, thank you. The first few (Mary, Crowven, and Twyla) I figured out—though in Mary's case, only because someone pointed out the pun in her name. Given Reginald's surname, I can see Pufferfish (Tetra, as a play on "Tetrodotoxin"). Vasilis is still a mystery to me, even so. But that does nothing to diminish my appreciation!
