Because I was talking about it in
townsenta's
spoilerrific Okamiden review and I thought I'd write it down. Please note that this isn't even the only Moon Tribe/Waka headcanon I have, but this is the one I'd like to write some backstory fic about. Mostly to reconcile the sequel butchery with the original, but never mind me.
