Adventure Tours

The single player mode for the Nintendo DS version of Mario & Sonic at the Olympic Winter Games has a set of Adventure Tours which revolve around a plot involving Bowser and Dr. Eggman's scheme to melt all the snow by capturing the Snow Spirits in Christmas Village.

Vector's Story
In Cubyrinth, Vector the crocodile is mentioned by Charmy when Mario, Sonic, 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.

Later in Icepeak, Vector is seen next to a mission sign. 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.

He is later seen again when he tells his friend to let him know how may 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.

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. The player is required to beat Daisy as Blaze and receives a crystal for winning.

After Toad mentions the Chao's Freezalea patch in Ice Peak, Daisy joins up with the team, "The flowers are blooming, then? I can't miss that! Let's go!". When they arrive back in Icepeak and Daisy is presented the Freezaleas from the Chao, she points out that she saw someone and Chao exclaims, "Kiki's going to destroy the flowers!". A wild Kiki begins trashing the patch and Daisy is prompted to complete a mini-game to chase it off, "I'm not going to let this happen! I'll chase it off myself!". Afterward, the Kiki runs away and in the process opens a previously sealed gate.

When Lakitu is encountered in Ice Peak, he mentions to Daisy that it would boost popularity of the missions he's in charge of if she were to compete in them. He also mentions that he will reward her the Meteor Curling Stone if she can complete the missions. The first mission objective is a Short Track event that must be completed in first place with no recovery zones. After completing it, Lakitu informs them to receive the reward, they will have to actually find the second mission and complete it as well. "Finding the mission may be even harder than completing it!", responds Daisy.

The second mission is found much later in Blizland and it is an Intense Short Track event. In the event, Daisy is required to reach the goal without falling from the course. Once completed, Lakitu will finally give Daisy the Meteor Curling Stone required to complete the final missions of the game, "Congratulations, Daisy! The crowd loved you!".
