The Chomping Monster Book of Monsters (76449) recreates Hogwarts' dangerous textbook with a buildable LEGO version featuring a furry cover, menacing eyes, and sharp teeth. The set includes a Neville Longbottom minifigure with his own miniature Monster Book accessory. A pull-back function with hidden wheels allows the book to race forward while its mouth chomps. With 518 pieces, the completed model measures over 6.5 inches (16 cm) long, 5.5 inches (15 cm) wide, and 2.5 inches (6 cm) deep. Designed for ages 9 and up, this Harry Potter-themed set can be built using the LEGO Builder app, which provides 3D instructions with zoom and rotation tools.
