All about this set

Older NINJAGO® fans aged 14 and up can add to their collection of LEGO® NINJAGO models with this stunning and highly detailed The Fire Knight Mech (71846) building kit. It features a dramatic scene of a cape-wearing, spear-holding mech locked in battle with an ancient monster emerging from the sea, and it will look great on display in a bedroom. Ninja fans can also remove the model from its base to recreate stories from the NINJAGO Legends Monstrosity series. The mech has posable features and the sea monster has movable tentacles. The model also comes with 2 NINJAGO minifigures: Kai with a magical sword, who can be placed inside the mech’s chest, and a fisherman with a paddle in a boat. The rest of the LEGO NINJAGO range of sets (sold separately) includes dragons, vehicles and temples for fans to role-play adventures with their heroes. Each ninja playset can be created with the LEGO Builder app, which guides you on an easy and intuitive building adventure. Set contains 996 pieces.

It's really awesome and so fun to put together! I think is the best Ninjago yet! Also it's HUGE. I absolutely love it and so glad I got to experience it, I never would have thought of purchasing a Ninjago set but excited to state I was wrong.
