Good Knight, Sir Kermit is a Muppet Babies book in which a restless Baby Kermit doesn't want to sleep. Instead, he pulls out a storybook, full of medieval adventures. He dreams himself into the book and meets his identical twin, Sir Dance-a-lot, and the pair switch places (ala Twain's The Prince and the Pauper). Baby Kermit duels a dragon for the hand of Princess Pigdowlyn. After a feast of dragon roasted marshmallows and grilled cheese sandwiches, Kermit wakes up.
