How do you become a demon in goat simulator?

Excuse me, but I have to ask, could you elaborate on the steps one would take to transform into a demon in the game Goat Simulator? I'm genuinely curious about the mechanics and process behind this unusual transformation. Is it achieved through a specific set of in-game actions, perhaps involving some secret cheat codes or Easter eggs? Or is it perhaps a random occurrence that players stumble upon by chance? I'd appreciate any insights you may have on this matter.
