On the show tonight a demon or something explodes in a school play, covering the audience with purple slime. Lot of cute females got covered.

Not so much "covered" as "meticulously applied..." some girl blows up, I guess, and splashes the front rows of the audience, Gallagher-style.

Here's three screenshots, with the brightness and contrast enhanced so you can see more of what's going on, since the scene takes place in a relatively dark auditorium. I've already deleted the source, it's not worth capturing... they don't show any of the people getting messy, and the shots these caps are from are 3-4 seconds long, back to back to back.

Not much screen time, but the expressions are lovely.
Nice find.
