Tweaks and adjustments are common in theme park attractions.
The abominable snowman was not added to Disneyland's Matterhorn Bobsled ride until more than a decade after it opened in 1959.
The Pirates of the Caribbean ride was remodeled in 2006 to include the likeness of Johnny Depp, who played Capt. Jack Sparrow in the popular movie series.
The latest adjustment of a Disney attraction is not that severe: Disney California Adventure Park has eliminated the giant beach balls from Luigi's Flying Tires.
