Boulderax is one of the five Rock Monsters from the Power Miners theme. He is also known as the green rock monster. Boulderax is not made from normal minifig parts and is exclusive and unique as he is only in one set. DescriptionEdit

Strong, slow, and dumb as a bag of rocks, Boulderax will fight a Thunder Driller just for the fun of it. Sometimes he gets so busy smashing the Power Miner's equipment that he forgets to take the crystals he came for!
