Willems and Codename: Kids Next Door creator Warburton allow readers to really get in touch with Pigeon, Duckling, and other beloved characters in a banter-filled activity book with a hilariously digressive narrative. On each perforated page, the Bus Driver provides instructions for each activity (which include drawing prompts, crafts, games, and more), while Pigeon-no surprise-gently pesters readers ("Now we''re done with this activity book, right?"). When an alarmed Pigeon announces, "We''re late for a puppet show!?" readers are instructed to craft a paper airplane, which then necessitates building an airport, naturally. Readers also have a hand in creating an elaborate puppet show (that Pigeon sleeps through), by filling in blanks for an exchange featuring a cranky new character, Mad Cow. The humor snowballs, with kids adding their own jokes to the mix, and the laughs will, too. Ages 3 up. Agent: Marcia Wernick, Wernick & Pratt. (Oct.)-PW
