The Monster Book of Monsters

Build the Monster Book of Monsters — a dynamic 3D wooden puzzle that snaps, rolls, and comes “alive” just like in the Harry Potter™ films. Wind the pull-cord to launch the book forward as its cover claps open and shut and its eyes pop up. A fun build and a striking display piece for every wizarding fan.
Assemble me. Open if you dare!

In Harry Potter and the Prisoner of Azkaban, the Monster Book of Monsters was an extraordinary textbook on the care of magical creatures, owned by Rubeus Hagrid™.

Its valuable information was fiercely guarded — the book would snap, growl, and even attack anyone who tried to open it without stroking its spine first.

The Monster Book of Monsters 3D wooden puzzle from the Harry Potter™ series by Ugears combines playful design with clever engineering. The model features a strap mechanism that locks the book in place. Wind the cord at the back to its maximum tension, place the model on a flat surface, and release the strap — it then rolls forward, its cover clapping open and shut like the snapping jaws of the original prop. For an extra wow factor, the eyes pop open just before full release, recreating the moment the movie book comes alive. This collectible mechanical model is both a thrilling build and a stunning display piece for every Harry Potter™ fan.
