Bart Simpson's Treehouse of Horror: Heebie-Jeebie Hullabaloo

In 1999, HarperCollins UK released a single, oversized comic special that collected the spooky, satirical spirit of The Simpsons' annual Halloween episodes into one standalone volume. Titled Bart Simpson's Treehouse of Horror: Heebie-Jeebie Hullabaloo, it gathered classic comic-book parodies and frightful fun from the franchise's long-running anthology series, offering a perfect, self-contained dose of Springfield's macabre humor for readers who wanted a quick, creepy fix.
