My name is Dorothy Ann. I am one of the kids in Ms. Frizzle’s class. Maybe you’ve heard of Ms. Frizzle. She takes us on lots of field trips in the Magic School Bus. We never know what’s going to happen when we get on that bus, but we do know that we’ll learn about Ms. Frizzle’s favorite subject-science! When Ms. Frizzle ordered skeleton costumes for us, some of the bones were missing. We headed for the Hugh Mann Costume Company to look for them. There, we learned why we need our skeletons, what different bones are for, and what makes them grow. But why was that strange skeleton following us? In this book, I tell you everything at happened on that trip, the time we went on THE SEARCH FOR THE MISSING BONES.
