While It's the Great Pumpkin, Charlie Brown may be among the most well known Halloween animated cartoons, there are many others that kids and adults alike might find fun to watch around the holiday. One example is The Simpsons: Treehouse of Horror Halloween special. Each year FOX airs a special Treehouse of Horror episode featuring spooky things going on around Simpsons characters. From cursed monkeys to evil robots, the annual special brings something new each time. Other Halloween cartoons include Garfield's Halloween Adventure and South Park: Ghouls, Ghosts and Underpants Gnomes.
