Mammon is DJ Hallyboo's true form
Basically, in one of the videos, it's shown that trying to connect to another DS with the pirated Mario Party results in the game connecting to someone called Mammon. Mammon is supposedly the demon of greed, which is something that while fits the theme of "people who pirate games are greedy irredeemable criminals", it's kinda random to namedrop a demon like him all of a sudden and then not make anything come out of it.Given how powerful DJ Hallyboo is, him being a demon is not out of question, and knowing him, revealing his true identity to the player to intimidate him wouldn't be something he wouldn't do.
