Fortress of Fear

The Fortress of Fear is the latest lair/home of D-Structs, Skrap-It, and-formerly-their allies in the Dinotrux series, appearing as a large cave with with a lava pool in the floor and various scrap metal elements constructed by Scraptools.

Season 2
After abandoning or being driven out of a number of other caves, the previous one having been incredibly cramped, D-Structs ordered Skrap-It to find him a new one in "Lair." The one Skrap-It selected proved suitable, but D-Structs insisted on some improvements and-against Skrap-It's protests-recruited a number of Scraptools to work on it, including Lloyd, Smash-It and Break-It.
