I noticed the mohawk difference too, but passed if off as one pic with her head up and the other head down.
Agreed, plus they raise and lower their mane....all the time. I have dozens of pictures and videos of that (minutes, seconds apart).
IF it were clear that one of the hogs simply had no mane/mohawk that would be different. But both photos show one. The rest of the hogs physique is just TOO dead on....for it not to be the same pig IMO.
