The Ghastly McNasty pirate twins are close to finding the long-lost treasure rumored to be buried in Little Snoring Castle. Lucky for them, they're not the only pirates in town—Little Snoring villagers sport cutlasses and eye patches, hoping to be hired as extras for the pirate movie being filmed at the castle. Posing as actors is the perfect cover for a couple of ghastly pirates trying to sneak into the castle...until best friends Hetty and Tat spy the duo. Can the kids outwit the nitwits? It's another wacky McNasty adventure but with 100% more sharks!
