"Watson has to be at Dirty Dog Groomers by 4:15 p.m., but no one can find him! Where could Watson be? Charlie and Lewis search high and low to uncover the mystery of the missing dog. With just 45 minutes left, they find a trail of cookie crumbs and drips of pink nail polish. They even set a pepperoni trap. Will they find Watson in time for his appointment at the groomer's? Only time will tell!"--Jacket.
