LEGO® NINJAGO® Rontu the Master Dragon (71842) toy lets ninja fans aged 7 and up recreate action-packed scenes from season 3 of the NINJAGO Dragons Rising TV show. This building set for kids features a dragon toy with a posable tail, legs, wings, head and jaw, 2 positions to place a minifigure on its back and a stud shooter under each wing. 4 NINJAGO minifigures are included in the LEGO playset: ninja warriors Lloyd, Sora and Wyldfyre, each with a ninja weapon accessory, plus Master of Misfortune, Zarkt, for kids to play out epic good vs. evil battles. There is also a brick-built mini shrine with a secret message that Lloyd reveals with his translucent reveal blade accessory. Sets and buildable action toys in the LEGO NINJAGO range (sold separately) include mechs, vehicles and temples so fans can role-play ninja action. Each ninja playset can be created with the LEGO Builder app, which guides you and your child on an easy and intuitive building adventure. Set contains 381 pieces.
I gave this to my 11-year-old niece, and it was an absolute hit! She is a true LEGO fanatic—she lives, breathes, and sleeps building—and this set really impressed her. Even for a seasoned young builder who has done it all, this Master Dragon (Rontu) was an engaging and rewarding project. She was especially impressed with the posability; once built, the dragon has incredible movement in the head, jaw, legs, and tail, which makes it look fantastic on her display shelf. The addition of the four minifigures (especially Lloyd and Sora) and the mini-shrine added a lot of play value, but for her, the joy was all in the intricate details of the build itself. It’s sturdy enough to actually play with but detailed enough to look like a collector's piece. If you have a child in your life who is passionate about LEGO, I can't recommend this enough. It’s a brilliant addition to any Ninjago collection! #complimentary #LEGO @influenster @LEGO I gave this to my 11-year-old niece, and it was an absolute hit!
