Explore marine depths with the LEGO Creator 3-in-1 Fierce Shark with a Treasure Chest (31381-1), a 379-piece set focused on aquatic life. The initial build presents a posable shark model, displayed on a stand alongside a treasure chest and a crab. As a Creator 3-in-1 offering, the bricks reconfigure into an anglerfish, complete with its own display stand and sea plants. Alternatively, the set constructs a posable manta ray, also mounted on a stand and accompanied by a clamshell. All three animal models function as display pieces, showcasing the set's rebuild capabilities.
