Your Personal Penguin by Sandra Boynton
First there's a story with a penguin that is just too adorable for words. It makes my heart swell it's so sweet. But it gets even better! There's a link to a download of Davy Jones (remember him? He was one of the Monkees) singing the story. It's a catchy tune that will be in your head for days, and one you will always find yourself singing when you read the book. I know I do.
