Underwater Robot

31090-1 Creator 2019 207 parts 0% catalog rarity Easy

The LEGO Creator 3-in-1 31090 Underwater Robot invites deep-sea exploration with its versatile 207-piece build. This robust submersible robot includes highly posable joints, a large transparent domed helmet with a distinctive red robot eye, and integrated ballast tanks. Its powerful left arm sports a functional claw and drill, while the right arm features a grabber, perfect for retrieving a golden nugget from the detailed seabed with its sea plant. Reconfigure the dome by removing the robot eye to reveal a cockpit control center for further immersion. Beyond the main Underwater Robot, this set offers two alternate builds: a compact Submarine for swift underwater missions or a sturdy Underwater Crane, ready for heavy lifting and recovery operations, alongside its companion buildable manta ray.
