Information on the location
Located under the streets of New York City, the sewer lair is the secret hideout of the Teenage Mutant Ninja Turtles and Master Splinter. Despite being located in such a dirty location, the lair appears comfortable enough for the TMNT to live in. It is furnished with a kitchen, living room with TV, bedrooms for the turtles and Master Splinter, and a dojo for practicing ninjutsu. It also has a workshop for Donatello and a meditation room for Splinter. It is wired for electricity to power the lights and stores many video games that the turtles have collected, as well as Donnie's power tools.
