Review for LEGO set 60123 Volcano Supply Helicopter from Brickset
“The small caterpillar-vehicle and the drill-station make a nice addition to the set. When you put a lava-stone under the drill and push down the drill-head, it fits into the small opening at the top of the stone and cracks it open. That's one nice little gadget. All in all,... More this set bears no surprises, just basic LEGO, which is nice, but not at this price!”
