For reasons unclear to us, a group of jellyfish is called a “smack,” perhaps due to the walloping pain produced by an aquatic rendezvous with some of the tentacled species. But fear not. Plunge into a dark, nighttime sea with a new puzzle from Nervous System that hides eight marine creatures within an entangled smack of harmless jellyfish.

The vibrant jigsaw contains 173 pieces, eight of which are playful whimsies that create a kind of hide-and-seek adventure. Handmade in the Nervous System studio in The Catskills, Jellyfish Dreams puzzle, along with a few other Nervous System miniatures, are now available in the newly re-launched Colossal Shop.
