Skeleton Inside You

From the back cover: "Halloween skeletons are just for fun, but the skeleton inside you is very real. Your actual skeleton is made up of 206 bones--64 just in you hands and arms. some of the bones are soft, but most are hard. Some are round, some flat, some big, others small. They all grow as you grow. Without your skeleton you would be like a big floppy beanbag that could not stand or run, jump or play."
