The Albino Penguin is an NPC in BLACKSOULS 2 you can encounter in the Mountains of Madness.
He’s most likely based on the Albino Penguins from the Cthulhu Mythos, which appeared for the first time in Lovecraft’s novella – At the Mountains of Madness.
You can only fight the Albino Penguin while your SEN is low. In the fight, he will attack you by increasing your SEN, and that will allow him to leave the fight as you won’t be able to fight him anymore.
