frank has been with us over a year now, its not normail muscles... i meant in the video you see it at 0:05 - 0:10. it looks like something is trying to push itself through franks belly downward...

i uploaded new video where you cna see it better at 0:12 - 0:13. please look again, it looks really weird.

its hard to see it in video, but its about one cm area that tries to push itself through franks stomach... just like in alien movie
