This has to be one of the most creative and best parties in Club Penguin. For April Fools Day, the Club Penguin Team made each room look completely different – from being upside down to being drawn by crayons. Thin Ice and Astro Barrier were combined into one game for the party, too. It was called Thinicetrobarrier. In the Club Penguin Improvement Project Servers (CPIP) penguins were turned into Puffles!
