Simpsons Wiki

The Simpsons' Treehouse of Horror (formerly known as Bart Simpson's Treehouse of Horror) is Bongo Comics's annual horror comic series based on The Simpsons. It is published in September (a month before Halloween), and takes its name from the annual "Treehouse of Horror" episodes of The Simpsons. The comics feature guest artists and writers, titles that are parodies of modern horror stories and films, and feature distorted versions of the people of Springfield like in the TV episodes.

In the UK, these are printed as part of the normal Simpsons Comics rotation. Some people call them the "Simpsons Halloween Annuals".
