LEGO Deep-Sea Research Submarine 42201

Exploring the depths.

What a robust build! The way the Technic beams articulate for that grabber arm is brilliant, showcasing some serious clutch power in those connections. I particularly love the pop of orange in the pilot's seat, visible through the large trans-clear dome, giving that critical sense of scale. The dual thrusters are poised, ready to propel this vehicle through the ocean's unexplored trenches.
