For the cutouts, I use SwfModify to extract shapes, movie clips, etc. from Club Penguin's SWFs. After that, I open the extracted SWF with my browser, zoom in (if possible), and take a screenshot. Lastly, I paste the screenshot into Paint.NET and use the "magic wand" tool to remove the white background.

I'm glad you asked that and hopefully this helps. :)
