Need Ideas: Wicked (The Musical) Themed Party

Sometimes I need help with planning a party too. I'm currently working on a Hunger Games themed party for May (my birthday month) but luckily, I've come across and even made up plenty of ideas for the day. However, a friend of mine has been in Spain since January and he will be back for about a month in July. I'm missing him a great deal and I can't wait to spend some time with him before he has to go back until December. He LOVES the musical Wicked, so I thought it would be perfect to do a Wicked Welcome Home Party!

Unfortunately, I've looked around and I haven't seen that many posts online about Wicked-themed parties. There are some Wizard of Oz ideas, but if you've seen Wicked, then you know those wouldn't ALL work or keep with the overall theme.

Here's the basics of what I'm thinking-

Green and Black colors
Green colored candy (maybe a candy bar?)
Cupcakes: Green for Elphaba and Pink for Glinda (or Galinda, if you will)

I figured I'd let this be my first post, while we wait for people to submit their own parties and for me to actually host some parties where I can post pictures!

If you want a particular discussion post, please let me know that as well. I love getting opinions from people on all sorts of party matters!
