I've finished all the puzzles, have more food then my villagers could ever possible eat, life is good for them... they just wander around having babies.
Lately, I dropped in to check on them and thought... wow, there sure are a lot of women... I picked one up and he made a male 'Hey!'.
I thought... hmmm... took a look at her info and... it was a man! I began looking at the other women and discovered... most of them were men too.
They have dresses on, bows in their hair, they're... crossdressers? Inbred? A bug? Hippies? Trying to start a new fad?
