Mosasaurus Dinosaur Boat Attack

🏷️ 77983-1•🎨 Jurassic World•📅 2026•🧱 703 parts•Intermediate

LEGO Jurassic World 77983-1 Mosasaurus Dinosaur Boat Attack turns Jurassic World Rebirth into an ocean rescue-and-attack scene. The molded Mosasaurus has an opening jaw, movable flippers and a swishing tail, ready to strike the cargo boat, helicopter or underwater drone. The boat includes a crane and tilting platform for deep-sea exploration, while Zora Bennett, Dr. Henry Loomis and Duncan Kincaid bring the movie characters into play. Accessories such as a flare gun, harpoon and drone controller give kids several ways to defend the catamaran or stage dinosaur action.
