<i>The Complete Peanuts</i> reaches the go-go mid-1980s with this volume: ''mallies'', ''punkers'' (Snoopy with a mohawk!), killer bees, and Halley''s Comet. The gang go to ''rain camp'' and ''survival camp'', the World War I Flying Ace comes down with the flu, Charlie Brown poses for a swimsuit calendar, Peppermint Patty gets a crabby tutor . . . plus Molly Volley, the unbearable, licensable ''Tapioca Pudding'', and plenty of Spike and his cactus!
