Sleezy made his debut inside of the Zombieville scare zone during Fright Fest 2016. He became a fan-favorite due to his unique interactions with guests, which led to him creating his own Instagram page.
For the final weekend of Fright Fest 2016, Sleezy had his right eyeball hanging out as a reference to The Walking Dead character Glenn Rhee's brutal murder by Negan in the Season 7 episode "The Day Will Come When You Won't Be", which had aired the previous weekend.
