''Youngsters are sure to delight in the exploits of this butter-loving pig, savoring the &;wonky in the extreme&; text and energetic, innocent art.'' &;School Library Journal

Some may find it wonky to take a pig to the drive-in. But not the Watsons, who think the movie&;s title, When Pigs Fly, is inspirational. And not their beloved Mercy, who is inspired by the scent of real butter from the theater&;s Bottomless Buckets of popcorn. As they pull up in their convertible, Mercy lifts up her snout and becomes a pig on a mission, leading a delirious chase that&;s trailed by hapless rescuers reunited from Mercy&;s earlier adventures.
