Where is Pennywise in Goat Simulator 3?

Excuse me, could you please clarify for our audience? I understand that Goat Simulator 3 is a popular video game, but I'm a bit confused about the mention of Pennywise. As far as I'm aware, Pennywise is a fictional character from the horror franchise 'It.' So, my question is, where exactly does Pennywise fit into Goat Simulator 3? Is this a reference to some kind of crossover event, a mod, or perhaps a hidden Easter egg within the game? I'm genuinely curious to know, as this seems like an unusual combination.
