MAGNA-TILESMAGNA-TILES 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.

DESCRIPTION

Undersea Adventure invites kids to imagine life beneath the waves as they build a multi-level underwater world. Using an XL baseplate, quarter domes, and quarter arcs, little builders can create bubble-like observation pods and tunnels for their divers and sea creatures to explore. Trapdoor squares and sensory tiles add motion and fidget-friendly fun, while decorative tiles—like ocean waves, jellyfish, starfish, clownfish, and angelfish—bring the reef to life. With two diver figures, mix-and-match flippers, and friendly animals including a dolphin, shark, sea turtle, and octopus with soft touch tentacles, kids have everything they need for endless storytelling. Fully compatible with any MAGNA-TILES collection, this set helps young explorers build on their curiosity about the ocean one adventure at a time.
