Mario & Sonic at the Olympic Winter Games
Egg Factory appears as the setting for Dream Short Track. The biggest change of the track is that it is now covered in ice, in contrast to the heated appearance in the original. Dr. Eggman's E-Series robots are also not present, instead the obstacles being crates and screws. The stage also appears different in terms of layout, showing the track in this game to be more of a figure-eight. Four ramps are placed at the end of the track right before the finish.
