Procambarus clarkii, known variously as the red swamp crayfish, Louisiana crawfish or mudbug, is a species of cambarid crayfish native to freshwater bodies of northern Mexico, and southern and southeastern United States, but also introduced elsewhere (both in North America and other continents), where it is often an invasive pest.

Since its introduction to California in the early 1900s, this vibrant crustacean has invaded streams and displaced top predators in aquatic ecosystems.

The Los Angeles River (Spanish: Río de Los Ángeles), historically known as the Porciúncula River (Río Porciúncula), is a major river in Los Angeles County, California. Its headwaters are in the Simi Hills and Santa Susana Mountains, and it flows nearly 51 miles (82 km) from Canoga Park through the San Fernando Valley, Downtown Los Angeles, and the Gateway Cities to its mouth in Long Beach, where it flows into San Pedro Bay.

While the river was once free-flowing and frequently flooding, forming alluvial flood plains along its banks, it is currently notable for flowing through a concrete channel on a fixed course, which was built after a series of devastating floods in the early 20th century.

During the channel construction process, 011668, a red swamp crayfish, is trapped under the concrete and undergoes a divine mutation.

Over 80 years later, performance art collective i8i accidentally penetrates the concrete codex to reveal the hibernating Angel of Treated Greywater.
