His role as Gibby, known for being shirtless during school hours, was originally recurring at his season one debut, until the character became popular enough to become a main character at the start of the fourth season, and a real friend and main co-star for Carly Shay, Freddie Benson and Sam Puckett rather than just another kid at Ridgeway High School. His younger brother, Ethan Munck, plays Gibby's little brother Guppy Gibson on three episodes of iCarly.
