LEGO Ninja Turtles 79117 Turtle Lair Invasion Building Set

The LEGO Ninja Turtles 79117 Turtle Lair Invasion Building Set brings the underground headquarters to life with 6 minifigures and an impressive array of interactive features. This 9-inch tall lair spans 18 inches wide, giving kids plenty of room to recreate epic battles between the turtles and Shredder’s forces. With Splinter, Donatello, Leonardo, Shredder, and 2 Foot Soldiers included, you get the core characters needed for authentic storylines right out of the box.

The lair itself is packed with clever mechanisms that make playtime more engaging. A hidden door and lockable sewer entrance let you control who gets in, while the barrel-dropping trap adds surprise attacks to your defense strategy. The surveillance room gives your turtles a tactical advantage, and the slide with lever-activated elevation creates dynamic chase scenes. When things heat up, the fan room features an exploding wall function that brings the action to another level. Storage areas keep all the included weapons organized, from silver swords and machine guns to the golden sword and bo staff. The convertible training platform with ramp helps your turtles stay battle-ready, while the cage with dropping door and slide-out stairs adds another layer of playability.
