Don't know about a Brain Fairy, but I've got a Music Marmoset that sits on my shoulder and occasionally rootles through my head to extract songs. Just wish the damn thing would sing occasionally - it must have a repertoire like Martin Carthy by now!

A kit-car builder called Guy Frazer-Stanisland invented the Lard Fairy. So far, it's not targetted me for a heavy campaign. Yet.
