“How much is that doggie in the window?” Clifford the Big Red Dog will visit Treehouse to celebrate the end of the “Dog Days of Summer.” Meet and take photos with the oversized pooch during a song and story time at 11 AM and again at 2 PM. Make a doggy-ear headband and “dog collar” bracelet in the Treehouse Art Garden and round out your visit with ParticiPlays in the Treehouse Theater at 12 and 3.
