his special begins with Linus roller blading around town. He roller skates to a birthday party and back. On his way home, he passes a garden, and hears a beautiful singing voice. He enters the garden to find the source of the beautiful voice, and finds a little girl singing (a version of "Mio Babbino Caro", from Puccini). Linus goes over to her, and introduces himself. She tells him her name is Mimi, and is visiting her grandmother for a while. Linus helps her in the garden, Mimi tells him how much she loves flowers and teaches him about them. After they finish gardening, Linus tells her he has just come from a birthday party, Mimi tells him she loves birthday parties. Linus then invites her to his birthday, which is in a few days, and she accepts.
