Cartoons that are depressing

What cartoons make you say "Holy crap that's depressing?" 

Noozles: Adventures in Koalawalla Land had a depressing ending. 

I thought everyone died in Care Bears the Movie II until I realized I had forgotten the ending.

Wasn't Lil' Bits supposed to be depressing? I remember some sort of natural disaster had happened or something? Gah. You can tell I'm really straining here. *steamsteamlol*
