01PLOT

In an ultra-tech lab, Dr. Marion Richards conducts some experiments on the U.S. Government research project named “Nanotech.” She watches a containment vessel through a powerful microscope as millions of microscopic robots, nanobots, disassemble a toaster and an alarm clock and then reassemble the pieces into something entirely different, a tiny, strangely human-looking contraption. Disgusted with the nanobots' acquisition of a personality, she electrocutes them and leaves the room. The nanobots take this opportunity to escape the containment vessel.

As the nanobots wander the street, it comes across a scene with a father and son buying a toy robot from a street vendor, Harry the Pickpocket. After ripping off the father’s wallet, Harry hurries down an alley, unaware that the nanobots are following him.

Harry slips on the bots, spilling the contents of his toy display case. As the toys smash into pieces on the pavement they are engulfed by the nanobots and re-assembled into a weird looking mechanical child, complete with a crude boombox voice. The strange creature walks towards Harry saying "Daddy" (a concept it learned from the boy) over and over. At first Harry is petrified but then he sees a demonstration of the nanobots abilities and becomes intrigued with the criminal possibilities.

The Turtles and Casey arrive at April's to help her move in. Since she has lost her job, April has decided to reopen her father's antique store, "2nd Time Around". Casey immediately rubs April the wrong way, particularly when he breaks a large cabinet of antique china.

Harry adopts the little nanotech creature and uses it to break into all sorts of shops, including several that are in and around April’s "2nd Time Around" antique store. All these mysterious and unexplained break-ins are causing April to be concerned for the safety of her shop, so she asks the Turtles to spend a few nights at her place. The Turtles gladly agree, both because April is their friend and because they are into the idea of a sleepover.

During the night, Harry and his nanobot accomplice do indeed break into April's store. Casey catches them as they leave, and Nano disassembles a car to create a new, more powerful body, and swats Casey away. Leonardo hears the noise and wakes the others. When the Turtles go down to investigate the noise, they run head on into Harry and Nano. A fight erupts between the Turtles and Nano, as the robotic swarm tries to help Harry escape. During the fight, Donatello manages to cut off a piece of the Nanobot with an old welding torch, and Nano reacts in pain.

After Harry and Nano escape, Donatello studies the piece and discovers the true microscopic identity of the strange robotic monster, as well as the fact that the nanobots reproduce at an incredible rate. The brainy turtle also discovers that the little nanobots are destroyed by extreme heat.

Deciding that they have to catch this nano-monster before it gets bigger and more powerful, Don develops a tracking device that allows our heroes to track Nano and Harry to a junkyard. The Turtles arrive in the Battle Shell and a full-scale war ensues between the 'bot and the Turtles. As Nano fights, it continually grabs pieces from the junk around it and absorbs the pieces into itself, growing larger and larger. The Turtles need to do something fast, before the nano-monster gets too big to defeat! Through teamwork, the Turtles manage to snag Nano with a giant junkyard electro-magnet. Harry spots this predicament and runs over to the crane, cutting its power in hopes of freeing his ally - but without power, the magnet drops Nano into a blast-furnace below, seemingly ending its twisted life outside the lab. Harry sees the end of his “child” and realizes he made a big mistake in the way he “raised” and used the innocent little nanobot. He says sorry and starts crying with police arrives and arrest the man. Poor Harry.

On their way back home, Michelangelo feels sorry for Nano, because he acted like a child. Donatello, who's driving the van, says that he feels sorry that young robot had such a "rotten" father. As they enter April's antique shop, to their shock, Casey and April start bickering with each other. Michelangelo decides to leave them alone....

06NOTES & GOOFS

When Nano threw Mikey onto the garbage pile, his nunchucks fell out, but he rolled down the pile and they were in his belt again.
In one scene, Casey has a red cast under his bandages, but in the next shot, it disappears.
In the scene where Nano is holding the Battle Shell, the image shows Leonardo at the wheel and Michelangelo in the passenger seat, but the scene before shows Mikey is driving.

07TRIVIA

In the beginning of the episode, when Dr. Richards was examining the Nanobots, they were making several shapes. One of which was similar to a Poké Ball from the Pokémon franchise.
