I was practising with my new wand (Willow, 10 inches, Unicorn Hair) when I noticed that when the Mobiliarbus spell was cast, a stack of boxes on the shelves moved. Hmmm...isn't mobiliarbus to move trees? Mobilicorpus moved Snape's lifeless body, so wouldn't mobiliboxen (or pseudo-Latin ending for box) move boxes? Trina (now working out to Harry on tape!)
