As Momo nervously waits for her first piano recital, she tells herself, 'I'll be okay... I'll be okay...' Then she hears a voice nearby, also saying, 'I'll be okay... I'll be okay...' It's a mouseling, who's nervous about her first performance, too. The mouseling invites Momo through a small door backstage, where Momo is amazed to find a miniature theatre filled with an audience of finely dressed mice! When it's the mouseling's turn, Momo agrees to accompany her on piano. The mouse audience is so appreciative! But then, as she rises to take her bow, Momo is surprised to discover - it isn't a mouse audience at all!
