Cody has built the Turtles a holo dojo to practice in, but as they eagerly try out their new virtual reality practice arena the power goes out in the building. As Don and Cody investigate a sentient computer virus called Viral starts taking over all the electronic systems in the building, including the dojo, trapping the others inside.
First appearance of Viral and Sh'Okanabo.
This episode provides examples of
- Back Stab: Raph stabs Viral's physical form in the back with his sai.
- Expy: The virtual elves and troll Leo fights in the beginning bear a strong resemblance to Link and Ganondorf.
- Another simulation in the dojo is an obvious reference to Wild West COW Boys Of Moo Mesa.
- Falling Chandelier of Doom: How Leo takes out the troll in the opening battle simulation.
- Hard Light: While at least some of the enemies in the dojo are physical practice bots, the inanimate objects and probably many of the other enemies appear to be this.
- Holodeck Malfunction: Engineered by Viral, holding Leo, Raph, Mikey, and Splinter hostage to force Cody to give up the password.
- Hurricane of Puns: Surprisingly done by Leo, of all turtles, as he lets loose with a stream of short-themed puns while fighting the elves, followed by a "Lights out, big guy" as he drops a chandelier on the troll.
- Lame Pun Reaction: Don to Mikey, when the latter says:Mikey: Hey, if you can't stand the heat, stay out of the kitchenbot!Don: Okay, that was lame even for you.
- Never Say "Die": Averted in this episode.Raph: Are we dead? This don't feel like dead.
- Unusually Uninteresting Sight: The power station workers, upon seeing a massive power spike resolve itself into a face that shrieks "FREEEEE!" Probably combined with some Bystander Syndrome.First Technician: What the heck was that?Second Technician: I don't know, but it seems okay now. Uh, let's take lunch.
- Unwanted Assistance: Raph feels this way about all the helpful AI appliances.
- Virtual Training Simulation: Cody's custom-built dojo for the Turtles.
- You Fight Like a Cow: Lampshaded by Michelangelo.Viral: You! You dare to mock me?Mikey: Yeah, it's sorta what we do in between kickin' butt!
- You Just Had to Say It: From Raph to Don, when the latter asks Cody if there was anything else in the building that Viral could inhabit while the power was shut off.
