The betels I can't find by me, I burry all my skulls but I think I'm gonna try cold water migration (? Is that what it's called) on a rat here in next few days see how that works. Far as references I don't have the books but I have found good stuff online and good pics so I think I can do it. I need a different drill and bit tho. Dude 3skulls that sounds like a fun job haha
