The opening mountain model combines building with subsequent play in the detailed interior of a hideout.

Key Features

• Plenty of pieces to build the mountain hideout – the set contains 271.
• Easy access to the interior thanks to hinges that allow the model to open up.
• The exterior features snowy rocks and movable trees.
• The play space offers a model over 13 cm tall, over 16 cm wide and over 16 cm deep.

Use / Assembly

During building, you can use the digital instructions in the LEGO® Builder app. This allows you to zoom in, rotate the model in 3D and track your building progress along the way. Once assembled, the mountain model can be opened up to reveal its interior.

The digital features make it easier to navigate the assembly of individual parts of the model.

Contents

• Three minifigures: Tony Tony Chopper, Dr. Hiriluk and Dr. Kureha.
• A table with equipment for experiments and medical books.
• Furniture, a writing desk and a chair.

The characters and interior furnishings give children more elements to play with directly inside the assembled hideout.
