Mining Machines were used in Munitions Forge in The Legend of Spyro: A New Beginning. Cynder had the Apes set up the mining machines inside Boyzitbig, the giant volcano on Munitions Forge. They are a darkish purple and some machines can be destroyed. Some machinery have spooky faces on them like Steam, the Conductor's manaical locomotive. The machines were presumably destroyed when Boyzitbig erupted.
