What will you really encounter? When you ride Expedition Everest – Legend of the Forbidden Mountain, you will barely escape the intimidating Yeti, but what will you really see? The actual Audio-Animatronic Yeti doesn’t move because of a problem with the ride’s foundation, he’s been motionless since not long after the ride first opened. Fixing the issue would require a lengthy refurbishment that would include taking apart parts of the mountain. While riding you will see the giant figure, and chances are that you will think that he’s moving, but he’s not. Disney uses strobe lights to create the effect, which has earned the character the affectionate nickname “Disco Yeti”.
