While photos of Invisible Irma weren’t permitted (she is invisible after all!), we did get to bring home some back-story on how Irma came into being. Oh, and a note to all those tween-agers at The Castle from our visit: She can play many other songs than just “Let It Go” (and you could have at least requested the Idina Menzel version, not Demi Lovato’s… ugh).
