The Milk People are the main antagonists of the Regular Show episode "Guys Night". They are small imp-like creatures from a dimension where people who do not complete the Milk Challenge enter.
History[]
The Milk People live in a void-like, completely white dimension. They have fang-filled mouths and can turn people into Milk People by biting them, but they wear visors over their heads to cover their mouths. When someone participates in the Milk Challenge without raising the jug over their heads after drinking the milk, their consciousness is taken to the milk world, where the Milk People serve them milk as a feigned act of hospitality. Their true intentions are to devour those who enter their world and turn them into one of their kind.
When Pops takes the Milk Challenge, he is sent to the dimension, where he meets several other men who also did not raise their jugs during the challenge. Pops helps them realize this and one of the men demands to know what is going on to a Milk Person. The Milk People then take off their visors and attack. Pops and the others put up a fight and escape through the elevator which takes them back to their world, but not before two of the men are turned into Milk People.
