What was the craziest cartoon(s) you saw whilst a kid?

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.
