The LEGO Creator 3-in-1 building set Treasure Hunt on the Seabed offers three different construction options from 522 pieces. The main model features a yellow research submarine with a transparent cockpit and a red giant octopus with movable arms. Alternatively, the bricks can be used to build a scene with a smaller submarine and a giant lobster, or a motif featuring a giant manta ray, a diver, and the seabed. An underwater treasure chest with gold bars and minifigures complete the set. The versatile building options allow for varied play and underwater worlds.
