Terrors of the deep sea, colossal octos earn their title by being as huge as galleons. One of these monsters is so incredibly huge and powerful that the whirlpool left in its wake can sink a ship—without the octo even attempting to attack it directly. Like its octorok cousins, a colossal octo is omnivorous. It spends almost all its time eating to support its massive frame, devouring any form of animal or plant it finds underwater.
