Saa-weet. The pictures are centered around the Adventure Party, which will take place in August.
Picture #1: It looks like an underground room or a party room.
Picture #2: Most likely a clothing catalog sneak peek.
Picture #3: Herbert? What is he up too now?!
August seems as an okay month... personally I thought more events would happen because a lot of kids are on summer break.
In other news, Club Penguin has introduced a new employee which will help them around the blog and post UK news. Her name is Daffodaily5.

Tell me what you see in the August sneak peek by posting a comment!
