This is a message from Polo Field:
Hello Penguins! Many of you have asked what party is coming to Club Penguin in August. We’ve also seen lots of suggestions...
“Make a Summer Party!”
“Bring back the Water Party!”
“Why not Music Jam?”

Stay tuned! We’ll be posting a special video announcement about the party next week on the blog. Until then... Waddle On!
…DON’T LIE TO US POLO!!! This is NOT a Classic Club Penguin Party! This as ANOTHER Takeover Party and it’s Advertising the Teen Beach Movie from Disney!
