Description
About this set
Rogue vs. Drix Race Car Duel is a 111-piece NINJAGO set made for the youngest builders, tied to season 3 of Dragons Rising. You get two cars. The ninja car has rolling wheels and two shooters with four darts, and the villains get a car of their own. A Starter Brick base gets things going fast.
Kids 4 and up can build it with little help, then race Rogue and Nya against Drix. It’s a nice first LEGO set for a NINJAGO fan. With the set retiring, sealed boxes will gradually get scarcer, which matters if you’re buying for a gift down the road.
Highlights
- Ninja car with rolling wheels and two dart shooters
- Four darts included for the shooters
- A separate car for the villains to drive
- Rogue and Nya with gold katanas, Drix with a reveal blade
- Starter Brick base helps young kids start building
