Miss Mousey made her debut in the 1974 special The Muppets Valentine Show, in which Kermit and Big Mouse vied for her affections during the song "Froggy Went A Courtin'." She broke both of their hearts when she instead rode off with Droop at the end of the scene. Although the name already appears in the lyrics of "A Frog He Would A-Wooing Go", she's referenced in the song when Rowlf the Dog performs it with Sam the Eagle in The Muppet Show episode 301. The Miss Mousey puppet, sans clothes and detailed eyes, appeared in the cast of Woodland Animals singing "For What It's Worth".
