Early life

Booger began attending Mixopolis Middle School.

First adventures

“Knock it off, Booger.” — Teacher He became close friends with Camillot after he decided to help him decide what seat he should choose in Mixing 101 class at school. He also played Murp Ball with Camillot in gym as part of the blue team.

Booger then went on a field trip to the Mixopolis Zoo with his Mixing 101 class, appearing in multiple mixes to help defeat the Mixeloptors set loose by Mixadel. ("Every Knight Has Its Day")

Saving the city and universe

Booger loved the city of Mixopolis. He admired the vibrant colors and its style of mixing. That was until the Nixels took it all away and spread negativity throughout the city. While he and his friends were in the Kid's Club, reading comics about the Nindjas, Booger tries to convince them that the Nindjas do exist. However, they do not believe him. As they wander through the city, they notice Mixels arguing and the Nixels painting posters advertising negativity. Soon, a building fire starts and Booger wishes for the Nindjas to save the Mixie Cat trapped in it. Witnessing them max to save the Mixie Cat, he tells his friends that they are real. He then notices groups of Nixels and familiarizes himself with them as if he had an experience with them before.

Later, Booger and his friends notice the new I-Cubit fad. His friends want to trade in their old Cubits for it, but Booger refuses, stating he does not want to live in a world without colours. Later, his town gets nixelized once all the cubits were traded with I-Cubits.

Still upset with the town's lack of color and creativity, Booger comes up with a plan to wear boxes and say "nix" to infiltrate the I-Cubit Building. They manage to get past the guards and get into the building.

As the inhabitants of Mixopolis have been completely nixelized, Booger and his friends reveal themselves to King Nixel. As the King demonstrates his I-Cubit scheme, boasting that he can win, Booger reveals his own Cubit. Shocked by this reveal, the King sends his nixelfied Mixels to corner the kids on a high platform. Although they are trapped, the kids do a coordinated group dance to reverse the effects of some of the nixed Mixels.

Booger swapping the I-Cubit with the last Cubit. With the Nindjas unnixed too, they max and help Booger. As the Nindjas distract the rest of the nixelized Mixels and an amalgamate of Nixels, Booger swaps the I-Cubit with his rainbow Cubit. This causes some of the Mixels to be unnixed. King Nixel then traps him in a missile; sending him off into the sky and taking away the essence of the city's color and creativity. However, it malfunctions; exploding and spilling the essence onto the city, turning it back to normal.

Everyone then mourns over Booger, thinking he is gone. However, he comes back in a parachute. He is then gifted the last of the Nindjas' comic book issues, with him as a character saving everyone, much to his delight. ("Nixel, Nixel, Go Away")
