Ocean life in motion

Alloy Construction

Alloy shells and metal components form each model's ocean-inspired shape. Material combinations vary by design.

Moving Mechanics

Motor-driven gears and linkages bring fins, flippers or tentacles into motion. Movement and controls vary by model.

Made for Adult Builders

Take time to fit the parts and assemble the mechanism. Check each kit's recommended age and difficulty before choosing your build.

Designed for Display

A display base holds the finished model while its mechanism moves. Give it space on a desk, shelf or in your collection.

From our metal model builders

Wow!  This is an amazing product.  Built well and worth every Penny.  My favorite part was the assembly of the product itself.
