I've made a video guide of all 10 squirrel locations (origin of pain DLC) / Achievement : "The Squirrels Have Rabies (20G) : Those sneaky squirrels are squeaking again. Can you find all the new squirrels on Paine Island ?".
I hope my video will help someone

Look at the description of the video if you need more details/help
