A year after Penny, K, and Luc rescued the Bawk-Ness Monster and a submarine full of cryptids from the nefarious Alvida Scales, they've reunited for what's supposed to be a low-key trip to the seashore with K's dad. K has big plans to follow in her great-aunt's cryptid-hunting footsteps and track down the mysterious Moby Duck with her two best friends in tow, but there are a couple big problems with this plan! First of all, Penny's also bringing a stranger along - a kid named 'Jo' who likes anime and video games and other things that K thinks are super boring. And if that wasn't bad enough, because of everything that went wrong on their last big trip together, K is forbidden from cryptid hunting of any kind! It's a disaster all around!
