The Search For The Missing Bones - The Magic School bus - No. 2 (Paperback)

Join Ms. Frizzle for a bone-building expedition in the second book of the chapter-book series, based on the popular animated show. When their skeleton costumes arrive without some of the bones, the class pays a visit to the costume company. There, they learn what different bones do, how they heal, and more, and even get a silly scare when a Halloween trick is played on them.
