Can skittish Roxie keep her big secret from fellow summer campers? Riding the bus with a variety of canine breeds (all in bright yellow T-shirts), long-eared Roxie looks nervous. She's afraid the others will tease her if they find out she's brought her blankie, hidden in her pooch pouch. All are nice and helpful except for Lacy, a tall poodle who tries to intimidate everyone. She steals Roxie's bunk in the Mutt Hutt and, when the two are Splash pals together, manages to overturn their canoe. The next day, her mean pranks continue; she disrupts the craft table, leaves her pooch pouch out for others to trip over and crashes into the Frisbee players. Later, Lacy doesn't show for Pup Paddle Time at the pond; reluctantly, a search party is formed. They find Lacy in the Mutt Hutt, clinging to her blankie. The shocked silence that follows is broken when Roxie bravely confesses her blankie secret. Soon every other pup follows suit—"Best friends rock both night and day / Camp K-9 pups, yip yip hooray!" Roxie's present-tense narration contains all the right details of both activities and feelings. Hayashi's clean pictures, in watercolor, pen and colored pencil, have a gentle look, apt for target audience. This empathetic tale should calm the nerves of all novice campers-to-be.
