This is what Billybob said on the official Club Penguin blog:
April Fools Party (special Server Test event extended!)
What a day! The April Fools Party launched today and there sure is a lot to see! I hope you get a chance to check it out over the weekend. There are tons of hidden surprises all over the island and a lot of the rooms have been redrawn in some really wacky and different styles! Be sure to check out all the different areas! Try getting together with a couple friends and see how many secrets you can find if you work together.
As always, let us know what your favorite part of the party is and even what you’d like to see next time. The party will be around until April 2nd! Have fun!!
In other news: Earlier today we announced a special April Fools event that would take place ONLY on Server Test between 10 am and 4 pm. After hearing from a lot of you about how much fun you were having with it, we decided to extend it! It will be up on Server Test all weekend. To check it out, go to clubpenguin.com/cpip and sign up for Server Test, login and play!
Until then…waddle on!
