Why is Stranger's voice acting so oddly paced and somewhat off? He's a Steef. A Clakker's conversation reveals that Steefs can't speak. Stranger had to teach himself how to speak the native language, but is not fluent.
Early in the game, Stranger says (with regard to his surgery) "I need this to survive." Once we know what the surgery is (Removing two of his legs to make him harder to identify as a Steef), his use of "survive" rather than "live" seems telling... It's because the Steef were hunted for a high bounty. Stranger himself might be aware that somebody is probably out there to hunt him.
In the final levels, Sekto repeatedly rants to Stranger that "The water is MINE". In the final cutscene, we discover that Sekto is actually an aquatic creature native to the Mungo River. He likely considers his natural habitat to be his, to do with as he pleases.
The fact Stranger's running animation involves him hunkering down and using his arms isn't just because, as a Steef, he's an alien centaur; it's because a recurring motif of Oddworld biology is unusual locomotion. In particular, Glukkons and Sligs both rely on their arms to move around, and correspondingly have large, strong arms but atrophied lower limbs; the Glukkons hide this under their outfits, whilst the Sligs compensate with their "cyber-pants". Look at how oversized and powerful Stranger's arms are in comparison to his revealed legs; Steef aren't quadrupeds, they're hexapeds! Using their arms and their four legs in conjunction is their natural way of moving at high speeds!
Stranger's bounty device converts enemies into ammo instead of saving them for turn-in later. The enemies are used as food for your ammo, which includes rabid furry things, bees, spiders, and spiked slugs. You get more ammo from live enemies. This begs the question if your critters had to eat your enemies in order to reproduce.
When you return to Farmer Beeks' Opple Farm late in the game, Meagly McGraw has taken over it and killed every Clakker that was living there. You can find all of their corpses littering the farm, except for one: Beeks' daughter. Outside of the farmhouse, one can find a fire, with a very large chicken-like corpse roasting on a spit. The obvious implication is that Meagly or his men are planning to eat Beeks' daughter.
