I don't know for sure, but I've had a look at this walkthrough on IGN (http://uk.ign.com/faqs/2006/shadow-the-hedgehog-walkthrough-673619) and it says they appear in several different stages, including Cryptic Castle, Central City, Sky Troops, The Ark, Final Haunt, and The Last Way. Hope that helps! It might be a good thing to add to the Black Hawk page.
