Mario & Sonic at the Olympic Winter Games (Nintendo DS)

Mario & Sonic at the Olympic Winter Games is a sports game for the Nintendo DS with a Wii version of the game released as well. Both games are a follow-up to Mario & Sonic at the Olympic Games. The game is produced under license from the International Olympic Committee in relation to the Olympic Winter Games taking place at Vancouver in 2010. Like the previous installment, this game is a collaboration between Sega and Nintendo featuring characters from both the Mario franchise and the Sonic the Hedgehog series.

Although Sega was handling most of the development for both versions of this game, as it did for the original Mario & Sonic at the Olympic Games, they were also handling publishing/marketing duties for all territories outside of Japan, South Korea, and Taiwan, while Nintendo has done publishing/marketing duties for Japan, South Korea, and Taiwan themselves.

While at Sparkleton, Luigi helps Mario and Sonic look for the key. A Boo scares him away, which makes Luigi bump into a tree. The key drops from the tree, and the Boo steals the key.

Tails' story
At Frostown, Miles "Tails" Prower knows Mario and Sonic is with him. He wants Sonic or Mario to challenge him on Ski Jumping match. After Tails is beaten, he wants Sonic to take him along, wanting to provide support. Meanwhile at Sparkleton, Amy Rose needs Tails's assistance; her rifle is broken, and she wants him to fix it for her. Tails does not test it prior to fixing it; because of this, Amy challenges Tails on Ski Shooting.

While the players are at Polastraits, a gate that is similar to the one at Frostown is present but Yellow Shy Guy wants anyone to try it if it works. Tails knows that the gate of Polastraits works, but Toad thinks that the players should head to Frostown to look at that broken gate. At Frostown, Tails can try to fix the gate. After Tails fixes the part in 15 seconds, the gate opens similar to the one at Polastraits.

Princess Peach's story
In Frostown, there is a Thwomp in the corner blocking the way. Toad suggests that they need Princess Peach to do something with Thwomp.

After Mario defeats Peach, she congratulates Mario for completing the mission and she joins the team. Toad then notifies Peach of the Thwomp in Frostown.

At Sparkleton, a Goomba has heard that Peach is good at Snow Machine Fight, but he wants to see Peach on the Snow Machine Fight himself.

Toad tells her that it is easier if she can show Big by demonstrating the mission, Alpine Skiing GS. After Amy completes the mission, Big says he is paying attention while Amy is skiing. He then gives Amy a Spark Luge he found while he was fishing to thank her.

Yoshi is found at Polastraits and he wants to be challenged on the Luge. When Yoshi is beaten, he congratulates Mario and Sonic and joins the team. Toad tells him about the lights in Sparkleton. Yoshi then arrives at Sparkleton, lighting the lights by sticking out his tongue. After the lights are lit, the gate opens.

At Cubyrinth, Yoshi tells everyone that it is easy to get lost there. He puts his Drift Board down and goes for a walk; he promptly gets lost and loses his drift board. Birdo finds the drift board that Yoshi lost and claims it is hers, despite Yoshi's consent. Birdo then says that the board has to belong to the top athlete, and gives the board back if Yoshi completes the Ski Cross Racing challenge.

Knuckles' story
At Frostown, Knuckles the Echidna is seen on a mission sign. He joins the team after they beat him at Biathlon. At Polastraits, he helps Cream the Rabbit open the chest. The chest contains a Fighter's Stick, but Cream gives Knuckles the stick after he wins the Luge mission.

Later in Icepeak, they find Donkey Kong crying due to the fact that one of his bananas fell in a deep ledge and he can't reach it. Silver then comes out and uses his physic powers to get the banana back to him. Donkey Kong thanks Silver and challenges him to Moguls in order to join the party. When Silver finally defeats him, he joins the party.

Toad tells him that there's a pole back in Polastraits. There are also obstacles on the pole, such as ice and bombs. When the ape presses the button on the pole, in their amazement, a bridge forms. Later in Icepeak, Donkey Kong asks Vector about his headphones. Vector tells him that he likes music in his own band. After beating Vector, Donkey Kong wants him to join the party.

Vector's story
In Cubyrinth, Vector the Crocodile is mentioned by Charmy Bee when Mario, Sonic the Hedgehog, and Toad run into him when the bee refused to let the trio get pass him. Toad then tells Charmy they will let him know when they see Vector.

He tells the trio he will join the group if Donkey Kong defeats the music-loving crocodile in a match of Short Track 500m. Once Donkey Kong defeats Vector, he then joins the party.

Toad then tells Vector that Charmy needs to see him back in Cubyrinth. When they arrive in Cubyrinth, Charmy tells Vector in order to open the gate, he must engage in a quiz based on Real and Dream Winter Olympic sports and the islands of the snow spirits. He tells him if he gets 5 questions correct within 45 seconds, he will open the gate and let them through. Vector succeeds, and they go through.

Espio is seen when he tells his friend to let him know how many more whitestones are there in Sparkleton, Cubyrinth, and Blizland. When all the whitestones are found in those islands, he gets surprised that there's none left when the player collects all of them.

Princess Daisy's story
Princess Daisy is mentioned when Mario, Sonic, and Toad run into a Chao at Icepeak who when asked about the patch of Freezaleas says he "promised to show them to Princess Daisy". Toad comments on how they should let Daisy know if they run into her.

It is later in Blizland that Daisy is found practicing her Ultimate Figure Skating. When Toad questions whether or not Bowser and Eggman brought her there she mentions, "I was just doing some skating in Blizland, and Bowser and Eggman showed up. They started making a castle and a base, and now look at the place! Talk about an unpleasant surprise!". She then explains how she has been in hiding. When she see's the "entourage" of help Mario has gathered she spots Blaze and they strike up a conversation that leads to Daisy challenging Blaze to a round of Ultimate Figure Skating.
