Amigo Pirates' submarine

The Amigo Pirates have an unnamed submarine as their ship.

Appearance
It is a green ship with intricate pattern designs, and their jolly roger painted on its front. Due to the ship being a submarine, it lacks a sail. However, the sides have paddle-wheels that allow it to move without a sail and underwater. It has a large periscope on the deck, and what appears to be gigantic harpoon launchers on the back, besides the main cabin. The back cabin has a large sombrero as a rooftop.

History
In the end of the fight between Largo and Monkey D. Luffy, Luffy smashed Largo through the ship with a Gear Third attack.
