Favorite Lost or Obscure Halloween or spooky media

I remember ben and jerry's used to have some really cool halloween flash games on their site. unfortunately most of the archives are broken and the games are now pretty much lost. some parts of it still work on the wayback machine, most don't. nobody seems to talk about about it anymore, which is a shame because i used to love their stuff when i was little.

Definitely the original opening to Halloween 5, it was really cool to finally see it after it was thought to have been lost for years(even if the audio had been damaged unfortunately, requiring Sean Whalen to voice Dr Death).

Also can't forget Crybaby Lane, which was arguably the original lost media search, I remember hearing about that film after reading one of the actors IMDB pages and wondering what the hell happened to it, then that same year someone found it and uploaded it on Youtube.

Also a big fan of the movie Hack-O-Lantern which is one of the rarest VHS types out there, regularly selling for over 100 bucks on Ebay.

Not the special itself but the music in "It's the Great Pumpkin, Charlie Brown" is lost to a degree. Its one of several examples where a production's original music exists only in a locked in form within the production itself and there are no album versions where the tracks are not intermixed with the audio of the movie/special/episode/etc.
