Answer for Larry about parents and traits
Larry it takes a lot of crosses to determine what parent passes what your looking for genetic wise
When I concentrated on polychrome I found that most things from Reckamp/Klehm would pass that trait, most likely from the years on inbreeding on Brother Charles part.
When I switched into the purple toothy type I had to find new parents that worked, the only thing I know for sure is that Men In Black, and Buddy's Vampire Lady give me the color I want but I'm still searching for big teeth.
All I can say is to watch for what you like and look for a pattern of what parents come up the most and try to find them as a base and go from there.
I-801 (Men In Black x Dad's Black Gold)
I-742 (Larry's Twilight Bite x Buddy's Vampire Lady)
