Actually what you see are the "travel machines" for degenerated mutants riding about inside them. These Kaled lifeforms were genetically engineered to perceive themselves as the ultimate lifeform. All other species are to ultimately "exterminated". The plunger is a multi-function manipulator, its seemingly simple design masking its true danger. the "roto-rooter" is a compact energy weapon that disrupts the internal organs and thus kills the victims. Sincerely, Bill

Tempt the Hand of Fate and it'll give you the "finger"!
