Mr. Rogers: It's fun for people to get together and make up things like plays, isn't it? It should be an interesting kind of musical play with giraffes, and elephants, and trees, and flowers, and whatever else the queen and princess make up. You can make up your own play, or you can make up your own song. Yeah, just sing about what you're thinking about.
All this talk of Princess Zelda being around for a long time isn't entirely accurate. Zelda Pulliam's only previous appearance on the series was as Ellen Paterson during "Work" week, five years earlier.
