I built this because of the mini mech, I then decided to make a pirate set that soon would turn into the mining machine. It is team of miners that are looking for ancient idols. (They also look for coal and gold.) I thought that it would make a cool LEGO set because it's a good sized build, it has an okay usage of LEGO pieces and elements and it just looks pretty cool to me.
In this set there is the main control center, the big mining machine and the mini mech with a small rock. This set includes four minifigures with extra hair for a two of them, two idols do lots of gold and coal.
