A little boat beached in a flooded harbor, the Leaking Brain caters to the Memory Junkies and Deep-Paris citizens that habit the surrounding area. The structure of the boat is surrounded by houses and shacks that have been built around it by the inhabitants of Deep-Paris.
Being built on top of a boat allowed the Leaking Brain to flourish a business as it could completely avoid the rising sea levels and constant climate change. The boat was also fashioned into a habitable location for some under Tommy's protection. Despite the handmade and "rustic" appearance, the Leaking Brain and its patron, Headache Tommy, are welcoming and accept all customers without prejudice.
