Peanut Butter & Cupcake Books by Terry Border
What's a little piece of bread to do when he's feeling lonely? Find a friend, of course! And that's exactly what Peanut Butter tries to do. But sometimes friends are hard to come by, especially when Hamburger has to walk his (hot) dogs, Cupcake is too busy building castles in her sprinkle box, and Egg laughs so hard he starts to crack up! Does Peanut Butter have a soulmate? Young readers will know the answer long before Peanut Butter does and laugh along with each mismatched pairing.
