Mayhem Maker

One time Vermin used it to put a bathtub on top of Princess Ugly's staircase.

A Mayhem Maker is a large computer bank capable of adversely affecting its environment, such as spontaneously generating a volcano or whipping up running water into a whirlpool. Not only that, its screen offers its user flawless surveillance of the area their chaos is being caused.

Vermin the Vile owned a Mayhem Maker. Too Close (Enough) for Comfort It appeared to be imported from beyond Gorkel, as an approved Mayhem Maker repairman called in by Vermin was neither a Gorkel nor of Vermin's species.

As Terry and his crew made their way through Gorkel's impenetrable forest, they were observed by Scavage, Vermin's familiar. Vermin used the Mayhem Maker to put some obstacles between the three heroes and his Domed City. His first obstacle was to trap them in tickle vines, but Robota freed them. Then, a crack in the ground formed a volcano spewing molten lava, but Omnus granted his friends safe passage. When they came across a placid stream, Vermin used the Mayhem Maker to turn it into a whirlpool, whipping them up and through the air to the outskirts of the Domed City. They were confined in a bubble cell, and Vermin mentioned that he had lifted the mist that had disguised the Domed City, but it is unclear if either was caused by the Mayhem Maker.
