Undersea Adventure 58 Piece Set

Dive into big-time imagination with Undersea Adventure, a 58-piece magnetic building set that turns any surface into a colorful underwater world. Kids can build domed observation pods, pop open trapdoor tiles, and send divers splashing into the scene alongside a dolphin, shark, sea turtle, and octopus. With new sensory tiles, soft coral and octopus tentacle pieces, and ocean wave graphics, every build feels like a brand-new deep-sea mission to explore.
