Dive into more than 100 monstrous LEGO® builds, activities and play ideas with this super-fun and creative set.

Use the LEGO pieces included and follow the ideas and instructions in the book to build a whole world of adorable monsters. All of the models can be made with the elements included and, if you want to make your builds even more awesome, you can add LEGO pieces from your own collection.

The book is packed with characters and worlds, including sky monsters, underground monsters, sunshine monsters, midnight monsters and deep sea monsters, all of which are simple to build.

Also included are lots of suggestions for creating your own monsters and taking them off on adventures of your own. Send a rainbow monster soaring up into the sky, build tools and gadgets for a mud monster and help a sticky-wicky monster find their way out of some slime! There’s no end to the scenarios, surroundings and silliness you can create.

Every activity features creepy creatures, funny faces and beastly builds, all specially designed to be achievable with the elements included and in five minutes or less. They’re perfect for indoor fun, whether it’s Halloween, a rainy day, or you just feel like making some cool LEGO characters!

The models are exclusive to this set and cannot all be built at the same time.
