A transparent pixel takes on the color of the pixel in the same positions from the background, which may have been determined by a previous frame of animation.
It may not be an alpha channel as with PNG, TIFF, and others, but I thought I remembered GIF supporting that in some way. Looks like I may have been halfway right, even if it's a sort of half-assed transparency.
