It’s the classic building block toy combined with the soon-to-be (possibly already?) classic building block video game to form LEGO Minecraft. This micro-set comes with 480 pieces and a tiny Player and Creeper.
Build your own microworlds…out of Legos. Then destroy them. It’s Minecraft in real life (sort of). You can combine multiple sets to build larger worlds.
This was some sort of limited edition set that sold out rather quickly but is available (at a slight premium, the set cost more than a normal set to begin with) via aftermarket sellers on Amazon below:
