Dream Ski Cross is a Dream Ski CrossDream Event that appears in the Wii version of Mario & Sonic at the Olympic Winter Games. The objective of the event is to complete two laps of the course in the fastest time, with the event taking place on Mario Circuit. To unlock this event, the player must reach day 13 in Team Festival mode. The starting record for this event is held by Tails with a time of 2:15.000.
In this event, the player starts by swinging the Wii Remote down when "Go!" appears onscreen. Doing so with perfect timing will allow the player to perform a starting dash and gain a short speed boost, however doing so too late will delay the player's start. The player can turn their character left and right by tilting the Wii Remote in the desired direction, and increase their speed by tilting the Wii Remote forwards to crouch. The player can stop their character by tilting the Wii Remote towards the to brake, and push off again by swinging it down. The player can cause their character to jump by swinging the Wii Remote upwards from a jump platform, and can perform tricks in the air by swinging the Wii Remote in any direction. After enough simple tricks have been performed, trick icons indicating a shape that the Wii Remote should be swung in will appear onscreen, and the player must swing the Wii Remote in that shape to perform a more complicated trick. Tricks can also be performed while airborne from boosted ramps and the Cannon, and the more tricks a player performs while in the air, the greater the speed boost that they will receive when they land. The more complicated tricks will also boost the player's landing speed further. The player can also use their special action, which grants them a short speed boost, by pressing . The player is given one special action at the start of the event, and the special action can be replenished by collecting 5 Coins once it has been used. The course also features Dash Panels, which give the player a short speed boost when hit and also angles the character in the direction of the course and a pair of Warp Pipes which transport the characters to the next section of the course. Goombas, Piranha Plants in Warp Pipes and Chain Chomps also appear as obstacles on the course, and will knock characters over if they hit them. Players can also collect the Item Boxes on the course to gain items which they can use by pressing . The player can obtain the following items:
Green Shell: Travels straight until it hits something and knocks over any characters that it hits. Can be defended against using a Super Star or Barrier.
Red Shell: Homes in on the character directly in front of the player and knocks them over when hit. Can be defended against using a Super Star or Barrier.
