<b>From the author and illustrator of the bestselling <i>Not Quite Narwhal</i> comes a sweet and funny story about remembering where you belong no matter how far you roam or what you're wearing when you get there.</b> <p/>Harriet <i>loves</i> costumes. She wears them to the dentist to the supermarket and most importantly to her super-special dress-up birthday party. Her dads have decorated everything for the party and Harriet has her most favorite costume all picked out for the big day. There's just one thing missing--party hats! <p/>But when Harriet dons her special penguin errand-running costume and sets out to find the perfect ones she finds something else instead--real penguins! Harriet gets <i>carried away</i> with the flock. She may look like a penguin but she's not so sure she belongs in the arctic. Can Harriet manage her way back to her dads (and the party hats!) in time for her special day?
