There's no telling what drove the infamous Black Gobbo to build this rickety contraption. The ravings of a single mad Goblin is bad enough, but such a power-hungry, malice-filled creature as the Black Gobbo can never hope to be understood. At first glance, it seems impossible that the ramshackle Black Gobbo's Speshul Destroya (The BGSD for short) can even function. Two crazed Night Goblins feverishly work towering cranes that swing wrecking balls made of fused cannons and scrap in twin deadly arcs. The half-thought out wooden structure creaks and groans under the strain and pressure of the two crane's erratic movements. The whole thing lurches forward under the uneven power of a Stone Troll pushing from behind.

To top it off, chained Dwarf captives (mostly Ironbreakers, 'cause they're heavier) are launched high into the air from a powerful slingshot seated between the swinging cranes. These poor Dwarfs eventually plummet to their death upon their fellow Dwarfs — a most shameful and grudge-worthy death. As such, the BGSD is a source of open hatred, causing even the most cool-headed Dwarf to fly into a rage upon sight of the infernal machine.
