I couldn't get the images to appear (they were red X's), so a link will have to do.

Yeah i have some screenshots of the same mob - Neilex here. I'm actually that fire person in the background so yeah. Going to upload diff pics of the same mob.

EDIT: Peggle's 2nd pic and my first pic are at the same time. Note the yellow flower and the skeleton's head (where it's looking)
