a lot of people arent fans of the oompa loompas being robots but i adore it. I always thought it would make a lot more sense if they werent an entire indigenous species thag mr wonka enslaved and paid in cocoa beans. this feels a lot more ethical. And the way they move adds so much extra eeriness to them. In this song especially, they force veruca and her dad into the chute, meaning mr wonka ordered them to literally murder them. if they were living beings, it could be blamed on the oompa loompas, but these are robots controlled by mr wonka, meaning all the deaths are directly because of him and that adds so much depth and hidden darkness to his character.
