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.
Compared to other Chinese donghua I've seen in the past, the show definitely feels a little more unhinged. Most things I see today are a lot more average, in my opinion.
