The Neighborhood of Make-Believe appears at a standstill. Lady Aberlin has the magic key that she hopes will open the door to a closed room in the Museum-Go-Round. What she and a couple of neighbors don't count on is that Lady Elaine is absent. All of them must wait for her return before they can try to work the key. Afterward, Rogers finds Bobby Rawsthorne demonstrating odd musical instruments at Negri's Music Shop.
