Annie still lives in the old apartment building.
Duke lives in carboard box outside at the front. Duke is an expert at getting to places around New York.
Duke is a small tan terrier with black spots on his back. He wears a red collar with a red triangle-shaped dog tag.
Annie is an old english sheepdog with hair covering her eyes, making it hard for her to see anything. She wears a black necklace with a pink heart-shaped dog tag.
They are both the only ones who seem to enjoy Scrappy's Secret Whistle (Scrappy whistles in a high-pitched sound which is so loud, everyone had to cover their ears, and it cracked the glass and blew out the tires on the Mystery Machine).
