Use / Assembly

The set requires assembly. When wound up and released, the book moves forward while simultaneously opening and closing its jaws, as if chewing.

The LEGO Builder app lets you zoom in on the model, rotate it in 3D, track your building progress and save your sets.

The product contains small parts and is not suitable for children under 3 years of age due to the risk of choking.

Interactive 3D guidance makes it easier to follow the build, and the finished mechanism moves without the use of batteries.

• The minifigure holds an accessory representing a small Monster Book of Monsters.
