Our DD#1 has a whole army of imaginary friends. The main one is Anio, he's been around for years. He currently lives in a whistle she owns (his previous homes include a roadsign nearby and inside her arm "with all the bones and blood") with his wife Sarah (who used to be a monster but now is half woman half pig).
At one stage the big bad wolf killed him and I actually found myself feeling sorry for him. But then he came back to life
