The Sky seen from the Ski Hill went a brighter shade of blue at the start of 2012.
Rockhopper never goes to the Ski Hill because he is afraid of heights.
During the 2006-2007 New Year's Party, there were fireworks at the Mountain. These fireworks returned for the April Fool's Day Party in 2007, coming out of a cardboard box. They came back again on July 4, 2007, which is the United States Independence Day, and Canada Day. They returned on July 1, 2008 and the last days of December 2008.
During the 2008 Medieval Party, half of the Mountain was decorated as a Black Tower. It has candle stands, flame stands, a lighted doorway and a magic mirror that gave messages like "Absolutely" or "No way" and similar words. It is extremely similar in the Medieval Party 2009, apart from the fact it has the Game Upgrades catalog and a Toboggan there.
During Operation: Blackout, first the sky was dark, then the post was covered in snow, and then the Ski Lift and the Grey Maintenance Shed were fully covered in snow. The sled rings were already kept and the cliff in the Penguin Run track was filled with snow.
