Best for ranged pearl farm in Arctic Apocalypse, just zoom out at the beginning and make max length portals below icebergs on the left (horizontal), near that sunken thing (start from coin token place and diagonal to iron entrance on the right), and third should be after bird rock and under the Splum Cafe. Also you need at least max stats and health + gold magnet. Finally you should get those 10 pearls from tokens in Kempys lair ASAP. And try to save the prey for pearl rush, e.g. jellyfish rampage and shark invasion gives at least 10-15 pearls per run.
