Dumb
The leading rat figure makes its way back to the carrier, whisteling and shouting something. Out of the carrier steps another rat-like figure, dressed in raggedy clothes and with a simular hood over its head.
The leader speaks some more gibberish before the raggedy rat runs in and grabs what sounds like a chain.
The raggedy rat scurries back out of the carrier, carrying a whip and pulling on a chain leading back indoors, then, you hear it.
Thumping sounds and screams like that of pain jumps out, as a large figure steps out, a head of a rat bandaged away. A monsterous build inhumane by any standards.

It steps out, pulling with it three crates, one of which is a tightly sealed metal crate, of which can be spotted having very high signs of radiation.
