bobs burgers is the most mature animated sitcom and isn’t marketed as “adult” so this checks out

I feel the same way about Tuca and Bertie, though that certainly isn’t intended for children and isn’t marketed that way, either. The show is horny and has a fair bit of swearing, but the actual themes and story beats are outright wholesome much of the time and speak to greater interpersonal truths than the types of self-described “mature” fandoms that recite “DAE LE POOPY BUTTHOLE GET SCHWIFTY” and the like.
