South Park
An episode called 'The Ungroundable' I think. Other than to highlight the brilliant
Fields of the Nephilim-type song about burning down Hot Topic, the only reason I mention it here is that in the scene where the chief vamp kid is being brought to Principal's office, there's a moment where he looks exactly like Bendy after Bloo's finally caught him out.
I suppose it's a coincidence of the 2 very simple character designs - 2 big eyes and a down-turned line mouth but just for a moment I could have sworn I was looking at my long last pal Bendy.
