Selva de Fuego whirlpool

The  is a whirlpool in a plastic container containing many aquatic plants that detoxify the Selva de Fuego river. Water from the river is pumped in through tubes, where the beneficial bacteria in the plant roots can clean the water, as well as the splashing of the whirlpool dissolving oxygen into the water. Then the water is pumped out back into the river. This whirlpool was implemented when the Fire Nation started dumping ant bodies into the river, which made it toxic, causing one of the Unnamed Guppy Fish Gang members to die from poisoning.

In June 2018, Mikey Bustos added three transparent shrimp, which he believed to be native to North America, into the whirlpool to clean up the dead bodies of the Fire Nation and some other decaying matter, including some nutritionist food for the fish after baby shrimp were born.

In July 2018, the whirlpool had transformed into a nesting territory for the Fire Nation to dig the soil for the additional space to live.
