iCarly

In 2007, Munck began a recurring role for three seasons on the Nickelodeon television series iCarly as Gibby, one of Carly, Sam and Freddie's friends. In 2010, Munck was elevated to a regular cast member from the fourth season onwards. In 2011, he was nominated for the "Favorite TV Sidekick" award at the Kids' Choice Awards.

Proposals were put forth in 2013 for a TV series called Gibby, a spin-off of iCarly that would star Munck. The series was to star Gibby working at a recreational center where he mentors four middle-schoolers. The series was not picked up, although Munck reprised the role of Gibby in the spin-off series Sam & Cat in 2014 for the episode "#SuperPsycho". Munck did not return to reprise his role in the 2021 revival series. His brother Ethan, however, reprised his role as Guppy in one episode of the revival series.

Munck also produced electronic dance music under the name NoxiK. He released his first song, "Beginnings", on January 20, 2012. Since then, he began to release songs he created to his YouTube account. He released a small EP called Hotline on April 23, 2013.^[6] On December 21, 2013, NoxiK released a single entitled "Killjoy" on SoundCloud and YouTube.

He released his first official EP titled Road Warrior on March 24, 2014.^[7] As of October 2017, the project has been inactive.^{[citation needed]}

Sadworld

On October 9, 2016, Munck started Sadworld, a YouTube channel dedicated to "weird, absurd" and experimental comedy sketches. The videos have a distinct editing style, described as "an amalgamation of images, glitches and sounds designed to overload viewers' senses."^[1] The channel has amassed over 11,000,000 views as of February 2024. Many of the channels' videos also contain music produced by Munck, which he releases on SoundCloud and other streaming platforms as Sadworldbeats.^[8] Munck also uploads longform videos of a similar ilk alongside collaborators Eric Bernhagen and Julian Clark on YouTube channel God's Abomination.^{[citation needed]}
