What items are you mixing in with the new Halloween stuff?

Right now I'm only increasing my Halloween area by adding the buildings and decorations. Once I'm fine with Bonus% and Layout I'll add some old decorations.

What I'm still unsure about is how to implement the egyptian stuff from Act 3. I already have a small egyptian area but it's far away from my halloween area and I don't feel like integrating it in my halloween area. On the other hand i don't like the idea of two egyptian areas in my game. Fortunately, I still have some time to think about this, but it won't be easy.
