Snow spirits

The Snow Spirits are major characters of the Adventure Tours in Mario & Sonic at the Olympic Winter Games. In the Story Mode, Bowser and Dr. Eggman are working together to melt all the snow in the Winter Games by capturing all Snow Spirits. Mario and Sonic team up to stop them and save the Snow Spirits. During the mode, Mario and Sonic meets several characters who will join them on their quest after completing their set of challenges. The Snow Spirits can be saved when beaten all the Rivals challenges.

It is probable that the Snow Spirits are the controllers, rulers, and maybe even creators of Snow.

Frosty
Frosty is the first Snow Spirit Mario and Sonic encounter. He is the leader of the Snow Spirits because of his determined attitude. When Mario and Sonic arrive at the top of Icepeak, Rouge is there to challenge them to a Figure Skating match. Bowser and Eggman appear with Blizza, Blizland's Snow Spirit and offer Rouge a larger whitestone if she challenges Mario and Sonic. Rouge accepts the offer and tells Bowser and Eggman if she doesn't win they have to give up Blizza. When Rouge is defeated she helps save Blizza, but Frosty is kidnapped by Bowser and Eggman. When Mario and Sonic arrive in Blizland, they have to defeat Dry Bowser. Once Dry Bowser is defeated, Blizza sneaks up on him and frees Frosty. At the end Mario and Sonic have to defeat Bowser and Eggman to end the Adventure Tours.

The next Snow Spirit is Sparky.

Sparky
Sparky is the second snow spirit Mario and Sonic encounter. Frosty doesn't leave after Mario and Sonic defeat Eggman Nega. Sparky has a jokester/wants everyone to be happy personality. He is energetic and full of life. He is the opposite of Blizza because he doesn't take anything seriously. He thinks that anyone who stands in Mario or Sonic's way is a piece of cake to defeat. After defeating Dry Bowser, he stays in his island, Sparkleton,in time for the snow festival and to keep the snow going.

The next Snow Spirit is Pola.

Pola
Pola is the third Snow Spirit Mario and Sonic encountered. Pola is a gentle, calm, and very sweet spirit. She lives in Polastraits, an island surrounded by water and ice. Pola is an opposite of Icy. She is determined to do what's right and doesn't make a fit. She is rescued after Mario and Sonic defeat Dry Bowser.

The next Snow Spirit is Cuby.

Cuby
Cuby is the fourth Snow Spirit Mario and Sonic encounter. He is an energetic spirit and always wants something to eat. He is rescued after Mario and Sonic defeat Eggman Nega (again). After Eggman Nega is defeated, he starts to teleport and gives Mario and Sonic Cuby. When he is gone he forgets that Cuby wasn't released out of the prison and Cuby falls right into the water!Luckily, Cuby saved his breath and he made it safely back to the surface. At the end Cuby leaves (for a lunch break)after Mario and Sonic defeat Big Bullet Bill (*Note: He is not the boss of the adventure tours) and the next snow spirit is released.

The next Snow Spirit is Icy.

The next Snow Spirit is Blizza.
