His sister Gunk is shown in Super Smash Siblings.
Grug made him Valley Leader in the series finale.
Munk is also known by his possible real name Theodore John Kaczynski this secret name was mentioned by the creator after a supposed interaction with someone that reminded him of the character, After this the creator was later found dead being possibly blown up by an I.E.D.
During one episode which was later deleted by the creator after only one day of airing on Netflix Munk was shown to be "infected" by a worm-like creature up the nose that greatly increases the victims intelligence. At the end of this episode it is shown when the worm is removed that they lose this intelligence. But in a secret scene only recorded once Munk supposedly stares directly at the camera and says "Do you really think I would need a worm to be intelligent? Do you really think that my intelligence can be removed so easily? Do you really think you are safe?" the credits do not roll after this he continues to stare until the episode ends.
