Permitted to get a pet -- but only one that doesn't need to be walked, bathed or fed -- Libby bypasses the "pet rock" option and instead orders the ultimate in low-maintenance companionship: an actual sloth named Sparky. That's the delightful premise behind Sparky!, the new musical at Lifeline Theatre. Even though Sparky doesn't know how to fetch and always loses at Hide-and-Seek, it's love at first sight for Libby and her South American friend. But after know-it-all Mary Potts mocks Sparky as lazy and unimpressive, Libby must throw a backyard talent show to highlight Sparky's (more subtle) skills. Be there for the first-ever "Trained Sloth Extravaganza!" and learn about accepting your friends for who they are, during this world premiere musical based on Jenny Offill's acclaimed 2014 book.
