LEGO Creator 3-in-1 Fierce Shark with Treasure Chest (31381) – Build 3 Sea Creatures | Ages 8+

Underwater Adventures with LEGO Creator 3-in-1 Fierce Shark

Dive into a world of imagination with the LEGO Creator 3-in-1 Fierce Shark with a Treasure Chest (31381). This 379-piece set invites kids to transform one build into three distinctive ocean characters, offering hours of hands-on storytelling and creative problem solving. The experience blends tactile building with dynamic play, helping young builders imagine vibrant underwater scenes while enjoying the satisfaction of a brick-built model.

Three builds from one set

From the same bricks, kids can assemble one of three sea creatures: a posable shark perched on a stand with a treasure chest and crab, an anglerfish on a stand surrounded by sea plants, or a posable manta ray on a stand with a clamshell. Note that only one model can be built at a time, inviting repeat creativity through rebuilding.

• Shark with a treasure chest for dramatic action poses and role-play stories
• Anglerfish with movable mouth and fins for undersea suspense
• Manta ray with a posable tail for graceful display

Play, display, and learn

The built models sit on a sturdy stand, turning each creature into aquatic decor for a shelf or desk. The LEGO Builder app adds a digital layer to the build—step-by-step instructions, progress tracking, and 3D rotation help kids explore the models while they assemble.

• Builder app provides guided instructions, saves progress, and lets you rotate models in 3D
• 3-in-1 versatility supports open-ended storytelling and pretend play
• Designed for kids aged 8+ with a mix of bricks, plates, and themed accessories
