Tangle mine

Invented by Sokka's father, Hakoda, tangle mines are made with a bamboo frame and covered with dried animal skin. Inside, the mine is filled with stinkfish and seaweed. These mines float in the water and detonate when a ship hits them. When the mines detonate, they explode seaweed and stinkfish. The seaweed tangles around the propeller of the ship, incapacitating it. Meanwhile, the smell from the stinkfish forces people to abandon ship. Though they are a very unusual mine, they are very effective. Hakoda calls them the stink 'n sink "It's destructive, buoyant, and terrible smelling".
