Step 5: Arms
Build the arms. Another simple step.
Step 6: Legs
Build the legs. If you don't, Nebulos won't be able to stand ;)
Step 7: Transformation
The transformation is quite simple, just watch the video in the intro of the Instructable. I may make a better video with my new camera, and get more in-depth, because the current video is a bit dark, blurry, and the music in the background is too awesome to care about every transformation detail ;)
