Egg Factory appears as the setting for Dream Short Track. Interestingly, despite the name, the setting is more akin to, an icy variant of Egg Factory, as it is covered with ice. Dr. Eggman's E-Series robots are also not present, instead the obstacles being crates and screws. The stage also appears completely 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.
