In my attic I've laid out little piles of each emblem, in a row (in alphabetical order, of course), as I continue to casually build toward icons. That just seems like the right place for them.
I had a piggy in my attic a few minutes ago... I re-captured her and let her out. I guess with a chicken you'd have to use animal youth potion to turn them back into an egg if they got stuck up there...
