The Turtle Lair is the home of the Ninja Turtles and their father, Master Splinter. The lair is located underground, near Big Apple Village. It appears in the Teenage Mutant Ninja Turtles x Naruto comic series.
To reach the lair, one must press a hidden panel at a closed cave entrance. This causes two large panels to separate, giving access to the cave. Once inside, a password must be entered on a location in a brick wall. One then stands upon a large metal grate bearing the Hamato Clan emblem which causes the grate to open onto a slide inside a pipe. The pipe spills into the lair entry, a large open space leading into individual rooms. Outside of the lair are sewer tunnels.
