Building the Adventure
The build process is as engaging as the play. Starting with the vessel’s hull, the set takes builders through a satisfying sequence of assembly—adding the crane, control tower, and submersible docking points. The vessel floats in water, allowing for bath or pool play, though most owners kept it on dry land for display and imaginative missions.
LEGO’s attention to detail shines here: the crane arm swivels, the sub detaches smoothly, and the diving gear fits neatly on the minifigures. Every feature encourages hands-on play, blending engineering creativity with roleplay excitement.
