The main show area was theater in the round style, with a large “teleportation tube” in the center of the room. Guests would sit in chairs with shoulder restraints (used during the attraction to imply that the alien was climbing over the audience, create intimate directional sounds of the alien breathing, and have the alien “taste” guests’ hair).
When the director of X-S tried to teleport into the theater, a slight error occurred, causing a horrific alien beast to arrive instead. The alien inevitably escaped, ran rampant through the theater, and guests barely made it out alive from their encounter. All the while darkly humorous dialogue from both the X-S staff and “other guests” were heard. Some memorable lines include, “Don’t eat me, eat that guy!” followed by a loud crunch. Or when the alien first appeared, “It’s ugly”, “It’s horrible”, “It’s my mother in law!”
The experience was one of the most immersive and clever in Walt Disney World, but its cult following was not enough to keep Disney from closing the attraction due to its excessively scary nature. In November 2004 the attraction was toned down and re-themed to become Stitch’s Great Escape, a horrible assault on the memory of this once great attraction.
We can no longer experience the magic of this show, however we can still reminisce while watching videos on Youtube. Here is a full walk-through of the show:
