Undarivik

So I'm making a level to celebrate... Uh summer and all, and I was wondering what sort of things should be in it. Obviously things such as palm trees and sand castles, but what else?

The more abstract, the better!

I have a good idea for a constest series, but I don't want to create it if no one will work on a level for it. What I'm asking is if I made this contest, would people join it?

Sorry for being secretive, if I make it I don't want details to get out.

One of the things I have the hardest thime in LBP2 is finishing my levels. Does anyone else have this problem?
