Fuck Gremlin

A tiny, mischievous creature who pops up in a character's ear whenever restraint starts to look boring, Fuck Gremlin exists purely to whisper 'do it anyway.' She's gleeful, unbothered by consequences, and treats bad decisions like a fun dare rather than a risk.

Big Mouth's whole trick is turning abstract impulses into gross, funny little bodies, and Fuck Gremlin is one of its purest jokes — a whole personality trait boiled down to a cackling id with wings. Jenny Slate gives her a squeaky, delighted menace that makes recklessness sound like the best idea anyone's ever had.
