Action-loving kids set sail for adventure with the Brick-Built Mosasaurus Boat Mission (76974) building set. Created for boys and girls ages 9 and up, this intuitive building playset lets kids assemble a fully-articulated Mosasaurus toy figure with movable fins, tail and opening jaw, a research boat toy, and a small ocean reef. Then, kids help LeClerc and Atwater minifigures stock their boat with story starter accessories like a syringe case and 5 sample syringes. Between pretend adventures, kids can repurpose the ocean reefs as stands for their LEGO dinosaur and boat toys. The downloadable LEGO Builder app guides kids on an intuitive building adventure, letting them zoom in and rotate models in 3D, save sets and track progress. Combine this set with the entire LEGO Jurassic World toy range, sold separately, for even Jurassic-inspired adventures! Set contains 858 pieces.
