Liana Island's last monkey statuette

In a post about the last (24th) banana, somebody said that the last item usually glows. It doesn't look like that's the case for the 12th monkey statuette. I've been over the entire big island a half-dozen times (somebody else says that none of the 12 are on a separate smaller island) and am just not seeing it. I found one at the right edge of a rock-pile that I hadn't even seen--I must have been moving the view when I hit it by accident!--so I've looked at all the other gray rocks, w/o success. It also took me way too long to notice the one leaning against the bottom of a pillar. Can anybody suggest a search strategy, say where the 2 or 3 other hardest to find are--perhaps partially or largely hidden behind something--or even point at a display of all 12 circled on the small map? 'Cuz if not, my only course is to start a new profile, because the game won't let me out. I knew when I went into this that I wasn't great at finding Hidden Objects, but I didn't expect to fail Chief Nartas utterly, without a clue!

Maybe one of these?

The first of them, as it happens. It was even pulsing when I went there right now. How I managed to miss it on the last pass--or maybe it hadn't quite gotten around to pulsing yet? Anyway (singing to a half-familiar tune), Guro, you're my guru, you're my guru, Guro, now!

Hello, I've already found 23 banana and I don't found any last banana. in the big island? I've already found anywhere, but still don't get it and actually it's easy to find because its colour is yellow. Anyone will help me with this?
