She’s lost her shoe again, and Treehouse needs her adoring fans to help her find it! It’s a visit from Cinderella! On Saturday at 1 p.m. Museum visitors can meet and take photos with the world’s most celebrated fairy tale princess in the Museum’s Days of the Knights exhibit. Crown making in Treehouse’s Art Garden and a participatory retelling of the famous fairy tale in the theater (11 a.m. and 3 p.m.) will accompany her royal visit.
