Down in the Technodrome Krang is arguing with Shredder about him going to the surface after Shredder found out that the urn that contained the ashes of the founder of the Foot Clan had been brought to display in New York. Shredder tried telling Krang that this was important for him because he possessed the scroll that could awaken the spirit of the founder of the Foot Clan.
Meanwhile Splinter and the Turtles see the same news report. Splinter tells his four students that he must get to that urn before Shredder does. When they get there they are too late. Shredder does something that causes Splinter to lose his memory. Then Shredder reads the scroll and the ghost of the founder of the Foot Clan appears. Raphael stays while the other turtles take Splinter back home to find a way to get his memory back.
When Leonardo and the others get their master back home and lay him down they start talking to him to try to bring his memory back. Leonardo tells his master who he really is a man named Hamato Yoshi who once lived in Japan and was the head teacher of the Foot Clan until an evil student named Oruku Saki made a move to get him thrown out of the Marshal arts school. Then Leonardo told him how he had moved to America and due to running out of money was forced to live down in the city sewers and had made pets of rats. Then he is told about how a boy walking along on the street above dropped a glass bowl that had 4 turtles in it and the turtles landed in Hamato Yoshi's lap. Splinter starts to regain some of his memory but asks for more information. Leonardo then continues on telling about how they all were mutated and they had then met April O'Neil the news reporter after saving her from some thugs. Then after the meeting of April how they started searching around and learned about Shredder, Krang, and the Technodrome. Splinter asks "Who is this shredder and is he linked to Saki?" Leonardo continues the story on how they had the first encounter in person with Shredder and he revealed that he was Oruku Saki and that he has his own mutants two of the thugs named Rocksteady and Bebop. Then Leonardo told him the origin of Krang and after the whole story was told their master fully regained his memory.
Splinter then said "There is one move that only the true leader of the Foot Clan knows and when I get there and do that move it will show the ghost that Shredder is not the true leader". Shredder is really getting things done to try to get Rocksteady and Bebop turned into ninjas and have them clobber Raphael. Then Splinter shows back up and calls out the name of the ghost and mentions the name of that special move that only the true leader of the Foot Clan would know. The Ghost agrees that only the true leader would know that move. When Splinter uses that move on Shredder the ghost then takes away the fighting abilities it gave to Rocksteady and Bebop and it shouted at Shredder saying "You are not the leader of the Foot Clan!" Shredder run away leaving behind the scroll and Splinter picked it up. The ghost thanked them for stopping shredder and it called Splinter by his real name Hamato Yoshi. Then as he told the ghost to go back to rest the ghost told them to come back and visit and as they started to leave the ghost's voice also said "Save the last slice of pizza for me!" That caught all five of them off guard that the ghost of Japanese man who has been dead for over 100 years would mention pizza. Then the five of them returned home knowing the scroll is in safe hands now.
