CURSE OF THE WEREWOLF (Haunted Shack): 
In the years prior to this particular theme, Haunted Shack mainly housed alien and toxic waste ideas. "The Curse of the Werewolf" was a well thought out, well decorated maze. Outside, the sets were designed to look like forests, while inside the mood changed into a renaissance type theme (complete with harpsichord music being played). One of the peaks of the maze was passing by a huge, mechanical werewolf, while other werewolves were "stalking" their prey. The mechanical werewolf could be seen recently in the attraction, "Bigfoot's Revenge".

INDUSTRIAL EVIL (Fiesta Village): 
1995 was the last year that Knott's used this space for Halloween Haunt. "WINDJAMMER" was about to be built, and one of the best sites for mazes was be to be lost. "Industrial Evil" was the beginning of what was to become "The Underground". Back then, more room was available for the maze to build bigger sets. All in all, "Industrial Evil" was basically the same maze as "The Underground", only longer. The music was the same as it is today, and the sets were primarily moved to this new location in Fiesta Village.
