Danger Mouse - I think the consistent 4th wall breaking, kidnapping narrators, and sense of humour as a whole had an effect on my from a formative age.

Monkey Dust - the cartoon that made it clear to me that cartoons weren’t not at all nesseccarily safe for kids. I was too young to appreciate it at the time, it was too disturbing for tween me.

Sealab 2021 and Excel Saga both crazy animations that I found easier to digest about that time, too.

Watership Down, other folks have already mentioned.

I think for me it was Robot Chicken that would play late at night

Can’t believe no one has said it… Looney tunes.

Grave of fireflies

Did anyone watch Liquid Television?

Invader Zim

Ren & Stimpy

I thing Dutch people from my generation have you all beat:

Purno de Purno (porn pun very much intended)

A psychedelic cartoon about a funny guy in spandex that has a shitload of nudity (tits, penisses etc) to the point of him even crawling in the vagina of a giant lady in space. It has references to litaral drug use. Have a look here: https://www.youtube.com/watch?v=4o6MIJ7Iq1U doesn’t matter if you know the language, just browse through. That episode is called ‘In het hol van de kietelaar’ which translates to ‘In the clitoris’ lair (hole)’

This was on kids tv. Nobody got seriously harmed by it. It was funny and weird, but you don’t really register exactltyy how weird it is untill you hear about sensitivities on US TV (nipplegate lol)

If we’re counting highschool as still a kid, the old Chinese cartoon Calabash Brothers. Still looking for ENG subs for the newer version that released in the 2010s, though.

It’s a cartoon where a snake and scorpion demon escape from a mountain and an elderly man has to grow a magic calabash seed that turns into 7 different calabashes that turn into little dieties when ripe in order to stop the demons.

For me it was probably The Head.

I really liked Duckman as well.

Also, the early Beavis and Butt-Head

True classics, haha.

Well there’s many mentions so I’ll add one I have yet to see listed, The Adventures of Mark Twain is always an unsettling classic.

Rocko’s Modern Life was a helluva ride

The oblongs, ripping friends, Ren n Stimpy, I r baboon were some of the best. Drawn together was a gem too that came out when i was a teen

Duckman, though that was not for kids.

Ren and Stimpy and Rocko’s Modern Life both had stuff that was bizarre and only allowed in a kid’s show because it was over their heads.

Batman TAS and Gargoyles both had some heavy shit. The latter also had a guy die by having fire erupt from behind his eyeballs, and a scene where a surgeon explains a gunshot wound in visceral detail. God I love that show.

Gantz, Watership Down, Animal Farm, Super Jail, and Urslua looks like my father’s mother, whom I hated, so I freaked the fuck out when my mom brought that VHS he.
