9In these paperback reprints, Rerun Van Pelt, born in our last volume, takes his first harrowing journey on the back of his mom's bike. The schoolhouse building Sally used to talk to becomes self-aware and begins to answer back. This volume also includes the classic Mister Sack goes to camp sequence. When Charlie Brown wears a paper bag over his head due to a rash, his alter ego, Mr. Sack, becomes more well-liked and successful than he is. Snoopy, Woodstock, and the gang enjoy several lively rounds of tennis -- which is why the legendary Billie Jean King provides the perfect serve with this volume's introduction.
