|Halloween Party 2005|
|When||October 27–31, 2005|
|Location||Book Room, Dance Lounge, Dojo, Ice Rink, Dance Club and Town|
In 2005, Screenhog was the only artist, so not much was decorated, except that there were orange lights at the Night Club instead of the white ones, and there were a few cobwebs around. The inside of the Night Club was also decorated. It had a few pumpkins and a bat hanging on the door. It also said "BOO" on the dance floor in yellow.
- On the What's New Blog, Billybob hosted a little contest on who can find the correct number of changes in Club Penguin. The first penguin who submitted the correct answer would get 500 coins in their Club Penguin account.
- The correct number of changes was 25, and the winner of the contest was a penguin named Charze.
