Mrs. Peters is missing! The Pee Wees’ leader has been called out of town on a family emergency. Who will run their scout meetings now that Mrs. Peters is gone? And who will help the Pee Wees plan their big Halloween party? Captain Spencer is the first substitute to take charge. He makes everyone march in a line and uses big words that nobody understands. Then there’s ditzy Brandi. She laughs at Roger’s dumb jokes and thinks slime-ball art is a fun project. Molly is sure there will be no costume contests or bobbing for apples this year. But then the Pee Wees get another substitute leader. And she has a plan to make this the best Halloween ever!
