Crocsquatch Achievement in Goat Simulator 3

You'll first need to complete the 'Bigfoot Sighted' event before you can do this achievement, located in the center of the map. Refer to New Goat Order (15G) for completing it. Once you're done, you'll have "Bigfoot" locked in a cage.

Now, head to Libertarian Island, up to the base of the giant statue (you can take an elevator up from street level on the west side of the statue). Near the edge of the statue area is a vendor with a green piece of gear near them. Pick it up to get the Fashionista gear. This lets you shoot at people with  to give them clothing.

Head back to the caged "Bigfoot" (you can zoom in where it was to see the completed green checkmark and mark it on your map again) and shoot at the "Bigfoot". Once you hit it, it'll give it a pair of shoes and you'll unlock this achievement.
