The lumpen, scarred stalker dolphins half-lurch, half-hop from freshwater rivers and lakes on rusting, rickety struts implanted grotesquely into their flesh.  They malevolently slaughter any and every Pure Human or Mutant Human they can with grasping pincers and snapping beaks.  Anyone attacking a stalker dolphin suffers a -2 To Hit, due to the creature's abject hideousness and madness-inducing squeaks.

For every 3 hours spent on land, stalker dolphins require immersion in fresh water for 1 hour.

Evidence suggests that the same unknown parties responsible for the stalker dolphins also created the ravenous rocketjaws.
