Plant Guy
A strange creature that wanders around in Six Flags Magic Mountain, though it never rides any of the attractions, it gets it's enjoyment by scaring various guests of the park. It is rumoured that it snatches children from rides when it is hungry. It is a paying guest, so Six Flags can't kick him out if you complain.
Guy: "Hey, the plant guy made my wife have an attack and then ate my son!
Worker: "Did you sign the waiver?"
Guy: "Yes."'
Worker: "Then deal with it."
