List of Teenage Mutant Ninja Turtles episodes
Back in England, the Turtles are listening to a historical lecture which Michelangelo finds too tedious to continue. To escape, he launches himself out of the castle in a catapult.
While the Turtles enjoy pizza, April leaves for Oxford to tape an interview with a famed historian. Splinter chides Michelangelo for his lack of interest in history, pointing out that seeds of tomorrow's events are the results of the past. They turn on the TV and hear a news report about the invention of an advanced atomic clock, which piques Donatello's interest.
That night, they sneak into the lab where it's kept, but as Donatello touches it, the device suddenly generates a whirlwind that deposits them in a strange, opulent observatory. A man snatches the atomic clock from Donatello and runs away with it, but not before revealing himself to be Professor Moriarty.
As the Turtles chase Moriarty, Sherlock Holmes and Doctor Watson also arrive and literally run into Donatello. The Turtles realize that they've traveled a century back in time, and Leonardo is thrilled to meet the real Sherlock Holmes in the flesh.
The legendary detective takes them back to Baker Street, only to be interrupted by Inspector Lestrade, who brings news of Moriarty stealing scientific equipment from all over Europe. Just then, one of Moriarty's goons shoots a bust of Holmes in front of the window.
The Turtles take a train to Oxford, where Leonardo uses his own deductive skills to track the would-be assassin down into the sewers. They soon find Moriarty's hideout, but he refuses to give back the atomic clock, which is a central part of a time machine he is building.
The Turtles find themselves in the present once again, but are horrified to find that armed troops are parading through the streets with the "emperor of the world," Moriarty. They're chased by his armed goons and end up in the river, then encounter an alternate version of April, who is working alongside alternate versions of Burne and Vernon to thwart Moriarty. Fortunately they know where the time machine is, and are able to take the Turtles there. April also gives a hungry Michelangelo an apple to eat.
Unfortunately, Moriarty has predicted their plan and is waiting for them. Donatello manages to grab the atomic clock in the ensuing fight, and another time-whirlwind is triggered that deposits them back in their own timeline. Moriarty is also there and tries to steal the atomic clock again, but the Turtles are able to stop him, only for him to vanish back into the past. Michelangelo tosses the atomic clock to the night watchman as the Turtles flee the building.
The Turtles return to the London sewers, where Splinter and April are waiting for them. Much to April's surprise, her bag holds an apple core.
