Guppy Gibson

Guppy Gibson is Gibby's little brother. His first appearance was in iPsycho (although he makes a cameo in the credits of iSpeed Date as a 5-year old Gibby who likes cheese). He is portrayed by Noah Munck's real life little brother, Ethan Munck.

Guppy seems to have similar tendencies to his brother, he likes taking his shirt off, and gets confused sometimes. Throughout the episode iPsycho, his main words were "Happy Birthday" to Gibby (after Carly, Freddie and Sam sent an S.O.S message under the guise of being a "happy birthday" message) although it wasn't his birthday. When Nora fights Gibby, Guppy cheers him on, and helps the iCarly trio escape from Nora's basement by unlocking the door for them. Guppy looks up to his big brother and sees him as a role model. He often likes to do exactly what Gibby does, some examples are that when Gibby comes out of the tent and stretches, Guppy follows behind also stretching. Guppy also like to take off his shirt like Gibby does.

He made a brief cameo in iSell Penny-Tees, eating the handful of spaghetti that Sam blew her nose into.

He appeared in iDo, when Gibby was on a bike ride, Guppy was in a wagon attached to Gibby's bike. When Gibby saw a $5 bill, Guppy stares at him. He even keeps saying "Happy Birthday" to him. Gibby asks him if it was his catchphrase. He also takes a keen interest in a girl that is passing by.

He has a cell phone as proved in iDo when he shot a picture of a young girl walking by, and when he calls his mom.

Guppy returns in iStart a Fanwar, and he is in the scene where he is in their car while Gibby and his Grandfather were trying to order soup. He kept saying "French Fries!!", singing old campfire songs, saying "My shorts are too tight!", and saying "I'm hearing the voices!!". Gibby is very annoyed by this.

Guppy often appears on iCarly.com, doing random things. Once he ate Spencer's hair.

He often laughs at the misfortune of Gibby, such as the time when he didn't get the money from the tree.

He also appears in the credits of iSam's Mom, sitting with Spencer and eating spaghetti.
