The Stadium Games "tied-in" with the Club Penguin: Game Day! release for the Nintendo Wii. Although the point of the Wii game is to "conquer the Island", the Stadium Games only takes place in the Stadium.
There was a big glitch in the Stadium, that about 10 error messages about Adobe Flash Player would pop up, and when you close all the error messages, the screen will freeze (for example, if you are walking, it would be like you are running at the same place), most dancing penguins would become Old Bluepenguins and making dancing moves that are a "hybrid" between break-dancing and normal dancing. This glitch was later fixed.
