"Oy, Willy Wanka', you can't do that, we are shutting you down!"

"But you haven't even seen just how undocumented my sexy workers are. Like, scientists haven't documented them yet, not even a name assigned to the species. Would you like to take one home & we forget about all these technicalities?"

"Are these people with dwarfism you painted & labeled a different species so you don't have to pay them???"

"No, I'm a factory owner, such allegations would be out of character for such an entrepreneur!"

Edit: didn't know, but they are just purple humans ... paid in beans ... cocoa beans, not lemmy beans (which as we know, do actually irl come from slave labour).

They are small humans who were preyed upon by the various predators that reside in their homeland before Wonka invited them to work at his factory. They are paid in their favorite food, cocoa beans, which were extremely rare on their island. The Oompa-Loompas are mischievous, loving to play practical jokes and singing songs which, according to Wonka, they are very good at improvising.
