Watership Down.

Was visiting relatives and we rented movies from a tiny video store that didn't have a lot of options or kids, so we got that and Crocodile Dundee.

Dundee was fun. The bunnies were less so.

cow and chicken

Do Saturday Night Live skits count?

The Ambiguously Gay Duo

Rocko’s Modern Life was a helluva ride

Ren and Stimpy

Beavis and Butthead

For me it was probably The Head.

I really liked Duckman as well.

Also, the early Beavis and Butt-Head

True classics, haha.

Ren & Stimpy

When I was like, 2? My parents were like "Hey! What's this new cartoon? Let's take the kid to the drive-in!"

Fritz the Cat:

The lord of the rings cartoon. I still don't know wtf it is.

I'm still not sure whether "Angela Anaconda" was real or a collective fever dream.

In my mid-teens, after Saturday Night Live they showed Fantastic Planet on Night Flight. That was an experience.

I was a kid in the 90's. It'd probably be easier to list the normalest cartoons. Like Doug.

Freakazoid, possibly. Or Toxic Avenger. Though the latter is more insane that they turned the original concept into something for kids in the first place.

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.

The Brave Little Toaster. It's a bit endearing until the LSD trip goes bad.

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)

The original sonic cartoon is like a chili dog induced fever dream

The old Nintendo cartoons, things like the Mario Super Show and the classic Sonic show. If you thought live action Mario and Luigi arguing with fungus people was weird, sometimes the people behind the cartoons would get so lazy that they wouldn't fully draw some of the frames or throw in a lazy scenario for the main characters like "what if Yoshi had a secret family he was hiding off-screen". Of note, people often ask me "why are you so relatively soft on the Zelda CDi games" and the answer relates to the deal of effort.

If puppet shows count, objectively it's Mr. Meaty.

The crazy stuff on Liquid Television

The Last Unicorn

Was Attack of the Killer Tomatoes real or did I dream that?

Oh, man, when I was a kid around 1990 I was in France (maybe? Pretty sure it was somewhere in Europe), and they had this subtitled cartoon (I didn't know either language) that "starred" a villain named something like Amin Tumani ("I'm in to money", but made into a name) that was a stereotypical middle easterner. And to add to the crazy I'm 99.9% sure he died at the end of every episode.

If anyone knows anything about this cartoon, LMK.

Can't believe no one has said it... Looney tunes.

The most hauntingly memorable was a weird mid-century Donald Duck piece of math propaganda. We watched it in school.

Donald Duck in MathMagic Land. Not scary, but odd.

Did anyone watch Liquid Television?

Probably the Toxic Crusaders, but only after watching the movie it's based on.

The cartoon itself is just another knockoff TMNT, which was the style at the time. I have no idea how someone showed a board of directors the Toxic Avenger in the early 90s and said, we should take this and make it a cartoon for children.

Ugh Probably Teens Titans GO: Its episodes just go from Fart Jokes to how to pay Taxes.

The Last Unicorn. Runner up, The Rats of Nymn.

Adolar's Fantastical Adventures

An old Hungarian cartoon about a boy who hides an inflatable rocket in his violin case. He uses it to fly to strange planets like a two dimensional one. Most vivid image I have in my mind is how the rocket stretches when it approaches light speed.

The first one that comes to mind is this one from probably the early 90s. From what I remember it was a group of kids and one of them is sick or something and the other kids try to save him? In the end they each sacrifice a year of their life so that the sick friend can live. I wanna say Steven Spielberg was a producer.

There was also that one crossover movie where a bunch of cartoon characters from whatever was popular in the 80s did an anti-drug movie.

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

Watership Down.

I saw a lot of Christian propaganda cartoons.

I remember there was a whole series where kids traveled through time to watch "historical" events.
