Considering their faces look like they were copied and pasted, it's no surprise that Gibby and Guppy are brothers in real life. While Gibby was portrayed by actor Noah Munck (Nicky Deuce), Guppy is played by Ethan Munck (Shrek Retold).

In 2022, Ethan Munck reprised his role as Guppy in iCarly Season 2, Episode 2, "iObject, Lewbert!." The official Paramount Plus episode description states that "Carly must defend herself in court with Spencer and Freddie's help after Lewbert returns seeking damages from injuries sustained on her old web show."

For those who don't know, the intentionally repulsive Lewbert (Jeremy Rowley) was Carly, Spencer, and Freddie's doorman and "archnemesis" in the OG iCarly series.

Lewbert has Guppy come to court as a witness, because he supposedly witnessed "the pain and suffering inflicted by Carly Shay on [his] brother, Gibby." Guppy doesn't have much insight to offer on the matter, however.

"I liked it better when I just said 'happy birthday,'" Guppy says, clearly hating being put on the spot.

Aside from his cameo as Guppy, these days Ethan Munck is still acting, as well as making his own music.

"I am back and doin amazing! Lots of new exciting projects coming soon and so much new music on the way," he wrote in a February 2022 Instagram post. Ethan's musical stage name is Kadet, penning songs like "My Heart," "Let You In," and "Always Trying, Always Failing" — all of which are available to stream on Spotify.

The musician's style offers a blend of pop, techno, and hip hop. His Spotify page states that "the former Nickelodeon star plans to shake off his Guppy identity with Kadet." Well, this guppy is now a full-grown fish.

New episodes of iCarly Season 2 release on Fridays on Paramount Plus.
