I really went and made a whole silly AU around this guy, didn't I?
Instead of going to therapy after being defeated by the Pines, Bill is sent to work in the Central IT department. He is literally cursed to work a 9-5 shift every 24 earth hours. The catch is that if he tries to avoid doing work or sabotages himself the clock resets and he's stuck there even longer.
He eventually resigns himself to escape the groundhog day nightmare, but with each shift worked he slowly loses his pigment, he is of course totally fine with this and taking it well!
I'm also 100% going to draw a human version because I think it's funny that he switches between the two forms. Mostly to avoid getting manhandled because he's like 5 inches tall as a triangle.
