After watching "Not What He Seems" for the eleventh time, I realized that in Journal #1, a page was shown that showed that the canyon of Gravity Falls was shaped like the outline of a UFO. So it got me thinking, what if Mabel and Robbie's clones (and maybe Stanley) were made by aliens that came through the portal? I know it's a bit of a long shot, but if you think about it, it kind of makes sense. Feel free to voice your opinion.
