Still recovering from his secondary mutation, Donatello feels cooped up inside the new lair. To help their brother out, the other Turtles decide to take Don topside to get some much needed air. The Turtles are then ambushed and captured by masked wooden warriors. The Turtles arrive before the Ninja Tribunal, four beings with a great resemblance to the Shredder. Along with four other warriors, the Tribunal entreats the group for aid against a greater evil.
