With 11,695 elements, it has the most included pieces of any set in Lego history. It's also mostly flat. Measuring 25.5" x 40.5", it's made up of 40 interconnecting base plates divided into three sections that can be arranged in three different ways to keep the owner's favorite part of the world in the center. The oceans are similarly customizable, with instructions for making a bathymetric-style mapping of the ocean floor, the option to create custom designs, and the option to simply leave them black for a more austere presentation. Arriving in stores on June 1st.
