Club Penguin has updated the games. Now, Sled Racing has music, and you can buy a toboggan sled. I personally believe this has ruined the game, because Sled Racing was one of the first games and this just makes it where it isn't a classic any more. They also added more music to Dance Contest (members-only) and they are much harder than the other songs.
When Club Penguin began, this is what the map looked like!!! Can you believe it???
