LEGO typically launches the majority of its new sets on the first day of each month. However, some releases don't follow this predictable schedule and arrive whenever they're ready. Today marks the arrival of three exciting new sets, headlined by a Mario Kart build. Here's a closer look at the LEGO sets hitting shelves on May 15.
