Krang and Shredder are going stir crazy. They have been defeated once too often by the Turtles, so Shredder has decided to do something about it. He takes Rocksteady and Bebop up to the Earth's surface and to the Asian-American Cultural Center where the burial urn of an ancient noble warrior and founder of the Foot Clan, Shibana-Sama, is on display. Meanwhile, April is doing a live broadcast from the same Asian-American Cultural Center. Splinter suggests that he and the Turtles should hurry there at once for fear that Shredder may be on his way. But they are too late. Shredder knocks the Turtles out with a ninja smoke bomb and releases the spirit of Shibana-Sama. Shredder requests that the Warrior Spirit teach Rocksteady and Bebop the secret ways of the ninja and make them invincible. Shibana-Sama replies that only the true leader of the Foot Clan can make such a request.
