Personality and traits
This unreasonably attractive gentleman goes by the name of Cap’n Cuttlefish. He’s a decorated hero who fought in the Great Turf Wars of legend between the Inklings and Octarians. He now keeps solemn vigil over Octo Valley, watching for any fishy behavior. Though his clothes may be tattered, his heart is pure and nothing escapes his razor-sharp gaze.

He can be found in the corner under a manhole in the Central Plaza.
