About LEGO Chomping Monster Book of Monsters
Hidden wheels and a pull-back mechanism bring this brick-built Monster Book of Monsters to life. Simply pull the book back on a flat surface and release to watch it speed forward with its mouth chomping rhythmically as it moves.
The 518-piece set recreates the furry texture of the book's cover using LEGO bricks, complete with prominent eyes, sharp teeth and menacing fangs. Builders aged 9 and up will find recreating these authentic details from the Harry Potter films provides an engaging construction challenge.
What's Included
The set includes a Neville Longbottom minifigure who comes with his own smaller Monster Book of Monsters accessory element. The completed model can be displayed alongside other Harry Potter sets or used for active play thanks to its mechanical action feature.
The finished book measures 16 cm long, 15 cm wide and 6 cm deep, making it a substantial display piece that captures the intimidating presence of this magical textbook from the wizarding world.
