Liz-beth is reading a book about bunnies, and decides that since Bunny does not eat carrots, he needs an eye exam. Liz-beth pretends to be an eye doctor, so she can exam his eyes. Then she pretends to be a teacher to teach Bunny his letters.
When Bunny asks Liz-beth where she came from, it leads to her bringing down the piano from Upstairs, and teaching Bunny and his friends some songs.
