Harold exists as three similar Audio-Animatronic figures that roar at the bobsledders; the first is visible from both tracks, while the other two are visible only from their respective tracks. Each track also features a pair of red eyes that glow in the dark shortly after the lift hill while Harold's roar is heard.
We didn't know they actually had a name, we always called referred to the TL side as George the Yeti and FL side as Elmer the Yeti. LOL I guess we will have to call them all Harold now.
