Early years (2000-2004)
10th anniversary (2009)
For Fright Fest 2009, Pigman became the main icon of the event for his 10th anniversary, where he appeared in Terror Train: The Legend Continues, and got his own haunted attraction, The Farmhouse Haunted Mansion. All over the park, signs could be seen referring to Pigman, telling guests to stay away.
The Slaughter House & Pigman's retirement (2010-2016)For Fright Fest 2010, The Slaughter House debuted, with Pigman as the attractions's main character again. He appeared in the attraction every year until Fright Fest 2014, when he was removed for unknown reasons. The attraction then took on a different storyline, treating the workers of The Slaughter House like bloodthirsty zombies than demented followers of Pigman.
- "We took Pigman out of the park several years ago, and even this year we'll get a handful of requests or questions about "Hey, where's Pigman this year?" So it's interesting how your guests will fall into that trap of wanting to have the same things year after year as well."

Return of Pigman (2017-2018)
After three years of fans demanding for Pigman to come back, Six Flags St. Louis finally announced his return for Fright Fest 2017 on their Instagram page on September 27, 2017. He returned as a character in The Slaughter House, and has stayed in the house through Fright Fest 2018.
Before he was known as Pigman, Mr. Drake was a pig farmer who lived in a pig farm on the property where Six Flags St Louis is now. Eventually, he was forced off of his land by Angus G. Wynne, a move that enraged him. After his death, Drake's spirit came back as a pig-faced demon, later known to everyone as Pigman. With his new form, he set off to attempt to destroy the park as revenge for his lost pig farm.
