LEGO Creator Fierce Shark with Treasure Chest 3-in-1 (31381) | 379 Pieces

Three thrilling builds in one set

Dive into underwater adventures with LEGO Creator 3 in 1 Fierce Shark with a Treasure Chest. This 379‑piece kit invites kids 8 and up to explore three distinct sea creatures from a single set, sparking imagination and storytelling as they switch between builds.

The set centers on a posable shark model that can be displayed on a stand with a treasure chest and crab. In addition, the same bricks can be rebuilt into an anglerfish on a stand with sea plants or a posable manta ray on a stand with a clamshell. Note that models cannot be built simultaneously, so play focuses on swapping between adventures and refining each build at a comfortable pace.

What you build and how you play

• Shark with treasure chest: posable mouth, body, side fins, and tail for dynamic displays and pretend underwater scenes.
• Anglerfish: movable mouth, side fins, and tail fin for expressive action in storytelling moments.
• Manta ray: posable tail fin to simulate graceful movement through imaginary currents.

Each model sits on an included stand, turning every finished build into a decorative display for a shelf or desk. This makes the set appealing as a birthday gift or a playful decor accent for a kid’s room.

Smart building plus interactive guidance

The LEGO Builder app provides kid-friendly instructions with progress tracking, zoom-in rotation in 3D, and the option to save sets as they build. This helps budding builders stay organized and enjoy a guided, yet flexible, building journey.
