The Server Testing of 2005 was a very small event in Club Penguin, where players could test brand new servers for Club Penguin. All players had to do was log on and click around to help look for bugs. During the testing, items were actually hidden in random places to thank everybody who helped test the servers. You could collect the Black Toque, Pink Toque, Red Sunglasses, Blue Sunglasses and the Black Bowtie.
- This is the least known event in Club Penguin, only being briefly mentioned in a Club Penguin History book.
- Similar events were the CPIP and Server Testing 2011.
- This was the longest server testing event in Club Penguin and it was one of the longest events ever, only being beat by the Stadium Games.
