In like a lion, out like a lamb!The morning bell has rung at Watertower Elementary School, and its time for Mrs. Pidgeons class to turn to page 52 in their science books to learn about one of the most spectacular scientific subjects of allthe human body! As usual, Gooney Bird has a special plan to make learning more fun. But what on earth is in that scary-looking box that her uncle, Dr. Oglethorpe, has brought to the second grade? And what does it have to do with the charms on Gooneys jingling silver bracelet? It looks as if another special story is in the works!
