Coming so close after the September 11 terrorist attacks on the US, Universal hurried to change the event to tone it down so it would be for accepting among the society at that time. Therefore the original mascot "Eddie" was scrapped at last minute. He was Jack's demented evil brother who led mass gangs of chainsaws, which explains the extreme amount of chainsaws during Halloween Horror Nights: XI. Eddie was replaced by the return of Jack. Taglines such as "Jack's Back" and “There's no more clowning around," were used. Anything graphic or violent was scrapped from the event, displaying no blood or gore. Names were changed left and right, everything from The Festival of the Dead Parade to the names of houses. Some original titles (which may still sound familiar) included "Bloodbath Underground" as what we knew as "Ooze Zone," modifications included red lighting being changed to green. "Scary Tales" was originally named "Terror Land." "Nightmare Alley" was originally titled "Slasher Alley," and the most obvious change would be the Festival of the Dead Parade being renamed as "Nightmares on Parade."
