As 'The Complete Peanuts' reaches its halfway point, Snoopy's family suddenly expands, adding a brother (Spike), a sister (Belle), and even a nephew. Also in this volume, the Linus/Snoopy/Truffles love triangle, Peppermint Patty's Powder Puff Derby and obedience-school fiascos, Charlie Brown's meeting with his idol Joe Shlabotnik, Marcie's unwanted suitor, and the final fate of the talking schoolhouse building.
