i only started watching adventure time really recently but i think it'd be up your alley in a lot of ways. short episodes, whimsy mixed with terror/weirdness, and a protagonist who can slip into autotune at will because he ate a computer once.
The clips I’ve seen have been dazzling. I have to make a point to check it out. I haven’t consistently watched a children’s TV show since Fillmore! so I have much to investigate.
