You dash into the living room, nearly slipping on a gumdrop. The cookies are fast—way faster than baked goods should be! One is climbing up the couch like a mountain goat. Another hides behind a pillow, snickering. You try to grab one, but it leaps into the air and lands on the dog's back like a rodeo rider. Your dog, Rex, looks very confused. "You'll never catch us, Oven Master!" one shouts. You narrow your eyes. You will catch them.
