Elephant & Piggie: I Am Invited to a Party! Mo Willems
Piggie is invited to her first party. She doesn't know what to wear, though, so she asks her best friend Elephant for help. Elephant's advice as to what Piggie should wear to the party is odd to say the least, so Piggie will try on all sorts of zany outfits before finally arriving at the party for a hilarious surprise.
