Nixel, Nixel, Go Away

"There it is... Mixopolis, my town. A city in spectacular living color. A city of mixing, for mixing. Here, Mixels would mix at the drop of a Cubit. The city was colorful and bright, and was always gleaming with new mixing possibilities. Mixopolis was my town, and it always would be. But then, things changed."

- Booger

Nixel, Nixel, Go Away is the fourth episode in the second season of Mixels, the twenty-fifth episode overall, as well as the series finale. It is also the fifth half-hour special. It first aired on October 1, 2016.

Synopsis
When King Nix [sic] puts a stop to mixing in Mixopolis, it's up to one young Mixel to save the city.

Act I
Introducing the city through narration, Booger reminisces about how wonderful Mixopolis is, showing how integral Mixing is to the community, through two neighbors, Sharx taking photos with tourists, Surgeo performing a medical procedure, and two teams of Kraws and Krogs. However, Booger notices that things have been changing, and Mixels have no longer wanted to Mix with each other lately, showing off a ruder personality towards each other as well as the colors of the city start to fade. Screeno is also one of the few that is disgusted by this depressing news. Booger notes how the city has gotten fairly bleak, but he knows that somewhere out there is someone that can help.

During a past bank heist of Brohawk and Punkchure, the two of them find themselves face to face with the Nindjas, the protectors of Mixopolis. As they Max and foil the two robbers, Mysto heeds the call for all Mixels to keep the balance of Mixing alive in Mixopolis as the Nindjas leave. This is later revealed to be a comic book being read by Booger, Zabo, Blip, and Scrud. While Booger is adamant that the Nindjas are real and will return again, his friends are not as sure.

While trying to convince them, Booger and his friends encounter two Nixels putting up negative posters for a new product, noting how the negativity is spreading throughout the town. During this, a fire in an apartment building has started, leaving a Mixie Cat trapped in the flames. As the MCFD are adamant about not Mixing with each other, the Nindjas appear and save the Mixie Cat, with only Booger seeing the truth, as hoards of Nixels stay and laugh at the destruction and chaos.

While the Nindjas question why the MCFD were so against Mixing, Booger notices the swarms of Nixels, and swears he has seen them before. Mysto pulls out a memory of a past encounter with the Nixels, specifically a battle between King Nixel, which means he is somewhere in the city.

Meanwhile, Major Nixel announces to King Nixel that the Nixels have infiltrated Mixopolis, which King Nixel wishes to make his own, through a product he calls the I-Cubit, which promotes conflict over creativity. With new devices, Major Nixel is able to convince nearly all of the Mixels to trade in their old Cubits for the new ones, which quickly drains them of color and enthusiasm. Despite the fact that his friends want to trade their old ones in, Booger is adamant to keep onto the one that they have.

When Major Nixel comments to King Nixel about how this remaining Cubit could cause problems with the scheme, King Nixel dismisses him, and sends his hoards of Nixels out into the streets. They reign chaos, fully turning the now-helpless Mixels into Nixelized zombies.

 * Cobrax: Yeah, but who?
 * Mysto: The answer is written on walls.
 * [Cut to the kids looking at a poster.]
