Nixel, Nixel, Go Away
The Mixamajig Key, a golden key with an eye on both sides of it, unlocked the Mixamajig.
King Nixel creates it and stores it in the Egg-Rock. Snoof then receives it from the Maximum Mixel shadow puppet hologram inside the capsule. King, disguised, explains to the group of Mixels that whoever has the key is considered "The Chosen One". Thus, many Mixels want a piece of it, so the key ends up in many hands. Later, it is used to unlock the Mixamajig before King Nixel does battle with the Maxes.
- It is suggested that although Snoof's story was focused upon, many Mixels went through a similar situation. This is shown in the scene where many Mixels (like Zaptor, Burnard, Globert, Seismo, Tentro, and Footi) congregate at the Mixamajig with their own copies of the key.
- The keys appear to be sentient, as their eyes move around and blink every so often, along with closing and looking at the bearers of it.
- It seems that in Mixopolis, there is a building resembling it.
