Now, I know from experience that the Sanguine's Goat tends to get odd on a lunar cycle (I actually monitored this with a clock mod for the game), though I don't remember what cycle exactly it was. I also know that the Dire Pony also tends to have glowing eyes and an oddity occasionally (possibly also on a lunar cycle), and that the Daemon Cockerel occasionally does red-eyes...are there any others? And does anyone else have specifics on what these cycles are? They could, theoretically be useful, (for people looking for bites, etc).
