[11] Intro: The Simpsons (all dressed as characters from previous Treehouse of Horror episodes, save Lisa, who is an axe murder victim) watch Kang and Kodos' lame attempt at a Halloween variety show.

I Know What You Diddily-Iddily-Did – In this parody of I Know What You Did Last Summer, the Simpsons accidentally run over and kill Ned Flanders, and end up getting away with murder -- until someone (or something) haunts them with claims that he witnessed the crime.

"Stretch Dude and Clobber Girl in: 'Enter the Collector'") – Bart and Lisa gain super powers (Bart gains the ability to stretch while Lisa becomes super-strong) after a freak accident during a candy inspection on Halloween Night in the Springfield Elementary School gym and must save Lucy Lawless (dressed as Xena) from the Collector (Comic Book Guy).

[63] Unlike the previous seasons, the Collector's Edition packaging is a removable molded face attached to a cardboard sleeve, as opposed to a fully plastic clamshell.
