the gremlins are the ones with the stripes on their forehead(what you call head spotted). they can be skinny stripes, and also fat stripes like the ones in the pictures. My pied ASF's sometimes have colored ears, but they don't have any color on the face most of the time.
In other words, I am assuming the ASF's pictured (especially the second picture) is not a pied, but a head spotted with a fat white strip) but it could also be a pied with more color then usual on the face? Don't know. I have about 10 in my grow up tub that look exactly like the ones pictured. can't remember what parents they were pulled from....
Ahh, see, it looks like a pied in the picture. As it has a white head and butt. :P
