there should be two to the left near the dock (iirc, it could be 3 but I think it was 2), two underground in the mines looking area directly below the hotel, another 2 near Gustav's grave, and the rest are in the trees/waterfall area between the hotel and the gravesite!!

some of the ones in the forest really like hiding behind trees + you may need to scroll out to get the one in the deepest part of the mine as it can get cut off if you're zoomed in too far :)
good luck on the hunt!

I'm stuck at 10/12. Does anyone have a good guide for where to find these colorful little critters?

There are 2 at the very bottom of the map on the hotel (Caverns)
Also 2 that are kind of hard to get behind the trees you can cut down.
