I've never seen any of them actually dying till now. They die when I'm away and I just see them lying there when I start the game again they wave goodbye.
My last peep (he has just died

) sent me an e-mail the last time I was playing telling me that he was not feeling well...

I gave him everything I could before I leave for work: fed him, gave him an orange, sunscreen, a hyper drink... He was 60.
