@Pokeguy: Welcome, and nothing: it is a stage 1 pokemon. It evolves from a ghost-humanoid thing that holds a pharoah's mask of sorts. And if you have any other questions like the one I just answered, I suggest using the "Pokemon BW Questions/Answers Thread" in the 5th generation sub-forum. There, you'll get an answer much faster and within a wider range of knowledge from people who actually have the japanese versions already.
On Topic: So Zuruggu is found in the desert...and it is *very*, very territorial. Doesn't bode well for me when I go treking through route 4 and the resort desert in search of crocodune and my avatar.
