Nick and Sally are wiggling and jiggling like the jelly mould in front of them. But they can't quite wiggle the same way. How come? Bones of course! announces the Cat. Bones keep their bodies from being wiggly and jiggly. But why do they need bones? A visit to Dr. Giggles will answer that question! They learn about the big strong bones that help us stand and walk, the small bones that help us bend and move, and the all important bones that help protect our squishy bits! Even though they won't let you wiggle and jiggle like jelly, bones are important!
