Sour Octopus

Fish Facts
The Sour Octopus is a variety of cephalopod found throughout NLACakaNM's marine habitats. For the most part, these are regular octopuses (octopi? octopodes?), highly intelligent, squishy, many-armed, and solitary creatures that use jet propulsion to move through the water. However, historical research into the origin of this variety of octopus has revealed that, of the original progenitor octopuses that ended up in the Slime Sea, a population ended up living near Slimecorp's fruity soda research labs hidden along the beach, and mutated the ability to change their flavor! Essentially, sour octopuses are equipped with special cells called "gustatophores", which secrete a foul-tasting sour chemical. The sour octopus uses this adaptation to its fullest, camouflaging itself as inedible objects or just overwhelming predators with sourness to avoid being eaten. It's an unconventional strategy, but it certainly works, as sour octopuses lack any natural predators, and can hunt for fish with reckless abandon. Of course, this makes them poor choices as seafood, but despite this there's a strong market for the secretions released by sour octopuses, which are useful as a flavor additive.
