I never get to drive the bus. I always want to stay up late and have a cookie. Who am I? The Pigeon of course! If you love me and my books by Mo Willems, come to my Happy Birthday Pigeon Party. The party goes from 2:00 to 2:45 PM on Saturday, May 11, 2013. This program is for kids ages 3 to 5 years old and their caregiver. Registration will begin Thursday, April 25th. See you there!
