Cloud 9 is the home of Pop Rocket in Skylands. No one knows where this is, due to the cloud being sooooo high. Only Sky knows where it is, but hasn't revealed it to Pop Rocket yet.
Nobody knows where the temple came from. Some think it was magic. Some think it was one of Kaos's evil plots. Some think it was a mountain. Not much information is known from this. However, all we know is that Soda Pop owns it.
