Lego Power Miners Granite Grinder (8958) for sale online ...
The Granite Grinder set by LEGO is a nice introduction to the Power Miners line, or addition to the collection. It''s the easiest means of picking up the Glaciator rock monster, for one. The set also includes a miner, of course, and the vehicle that you build has a neat pulsing, "drilling" action when you push or pull the vehicle around.
