This is a submarine that I created based off of the color scheme of Stampylonghead with a full interior with several decks - including a magic power source reactor, a torpedo room, a command center, and much more. Feel free to use the schematic download for whatever you want. *YES, IT IS MADE OUT OF WOOL*

Not based off of any real submarines- according to the dedication plaque on the bridge, it's a Longnose class attack submarine :)
