Cookie Monster is wrongly accused of stealing world-famous masterpieces in this hilarious parody set at the Museum of Modern Cookies. Detective Elmo, Chris, and the gang try to clear Cookie's name as the scrumptious paintings are stolen right from under their noses. As the adventure heats up, tour guide Prairie Dawn shares stories like how the great artist Leonardo da Crunchy made Muncha Lisa smile. Cookie also learns important self-regulation strategies-about cookies, of course!-along the way. Discovering clues, following a lead, and a little magic are what it takes for Elmo, Chris, Prairie Dawn, Abby Cadabby, and Grover to save their friend and find the real "Cookie Thief". Includes special guests Rachel Dratch and Terry Crews plus OK Go's vibrant Primary Colors music video.
