Penny swears that when she was a little girl, a creature called the Bawk-ness Monster—half sea-serpent, half chicken—saved her from drowning. Now, years later, she’s about to move away to a new city, and before she goes she needs the help of her best friends, Luc and K, for a vitally important mission: to help her see “Bessie” one more time and prove that what happened was real. But in their quest to find Bessie, the kids stumble into a whole new problem—cryptids are being kidnapped by an evil collector, and only Penny, Luc, and K can save them!
