Magna-Tiles Undersea Adventure 58-Piece Set

MAGNA‑TILES® Undersea Adventure

The ORIGINAL Magnetic Building Brand.

Dive into deep‑sea storytelling with MAGNA‑TILES Undersea Adventure – a feature‑packed ocean building set designed for big imagination and immersive play. This 58‑piece set lets kids create a vibrant underwater world with domed observation pods, winding tunnels and splash‑ready trapdoors, then send divers and friendly sea creatures on exciting missions beneath the waves.

Easy to assemble with MAGNA‑TILES’ signature magnetic design, Undersea Adventure is made for bold, multi‑level builds and interactive exploration. With ocean‑inspired colours, wave graphics, sensory tiles and soft‑touch coral details, kids can design dynamic undersea habitats while naturally exploring spatial thinking, problem‑solving and early STEM concepts through open‑ended play.

What Is Included: 58 magnetic pieces, including two diver figures with flippers, four sea creatures (dolphin, shark, sea turtle and an octopus with soft‑touch tentacles), an XL baseplate, quarter domes and quarter arcs, slides, trapdoor tiles, sensory tiles, soft coral pieces, arch windows and decorative ocean‑themed tiles.

What Makes It Unique: A large, immersive ocean set that combines multi‑level building with character‑ and creature‑driven storytelling, plus sensory and motion features – giving kids a complete underwater world to build, explore and rebuild again and again.

Developmental: Encourages imaginative storytelling, role play and early curiosity about ocean life while supporting spatial reasoning, problem‑solving and fine‑motor skill development through stacking domes, connecting slides, positioning animals and redesigning pathways.

Great for Gifting: Perfect for ocean lovers, animal fans and budding marine explorers aged 5+ who are ready for a big, centrepiece set filled with creatures, characters and interactive features.

More to Explore: Combine with Dolphin Bay, Shark Dive, Coral Reef, Lighthouse Rescue or classic MAGNA‑TILES sets to expand play from an undersea station to an entire coastline of reefs, bays and rescue adventures.

Always Compatible: All pieces are fully compatible with other MAGNA‑TILES sets, allowing kids to mix, match and build bigger worlds every time they play.
