Spike is drafted into the Infantry (in Snoopy’s imaginary World War I army), and a brand new Snoopy brother, “Marbles” takes his bow. We also see two major baseball-oriented stories, one in which Charlie Brown joins Peppermint Patty’s team, and another in which Charlie Brown and his team lose their baseball field.

In other stories, Peppermint Patty witnesses the “butterfly miracle,” Sally (in an unrelated sequence) gets fat, the Van Pelts get into farming, and the hyperaggressive Molly Volley and the whiny “Crybaby” Boobie, make a return engagement.
