Lu and Clancy aren't thrilled about babysitting Lu's little sister, Sophie, and her friend Fanny. But when Sophie mysteriously disappears, the dog detectives must spring into action. Kids help Lu and Clancy as they search for Sophie -- and learn about the science of sound at the same time. They will figure out how far away a thunderstorm is, use sound vibrations to make a bug buzzer and build junk band instruments, including a tin drum and a kazoo.
