What It IsThis is LEGO's newest original theme. It's all about burrowing into the earth to discover a world of action and adventure full of unusual creatures, strange and mysterious crystals and Rock Monsters who are always ready to do battle. This system combines collectibility, an engrossing action/adventures storyline and bold new colors that are dramatic and new for LEGO. This is a whole system that kids can build a piece at a time, and, of course, it works with all other basic LEGO pieces to inspire virtually endless creative play.
The Thunder Driller is a powerful machine that turns rocks to dust. It has a pinning dual drill head that actually mirrors the opposing rotation that would be found in a real drill of this nature, and which we found completely fascinated kids. Of course, in an imaginative sense, it's great to keep kids playing and creating. The 235-piece set comes with floodlights, walkie-talkie, 2 crystals, 1 miner minifigure and 1 boss minifigure.
