Egg Factory

Egg Factory is a race stage from the Sonic the Hedgehog game Sonic Riders, where it is portrayed as a fiery factory stage with Dr. Eggman's E-10000 series robots patrolling it. In Mario & Sonic at the Olympic Winter Games, Egg Factory appears as the setting for Dream Short Track. Despite the name, the setting is more akin to, an icy variant of Egg Factory also from Sonic Riders, as it is covered with ice. Dr. Eggman's E-10000 series robots are also not present, with the obstacles instead 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.
