If you need a good amount of poly, I would highly suggest going to the arctic and flying around the islands at that place. Make sure you can craft multiple clubs, as they give a lot of poly. (You can also use pelagornis or whatever you want to use.) I would not suggest using a snail, as they don’t give much poly (about 1-2 to be specific) and give more cementing paste. It’s a good method to kill a lot of penguins with clubs to get a lot poly, and the younger it is the more poly, so if you find a baby penguin it could give over 20 poly from that one corpse where an adult could only give about 10-15, and if your lucky then 20. Make sure to bring an otter or fur armour, as the arctic is cold.
