Creek Kids who have no major roles and are too insignificant to have their own pages.

Greg and Chelsea
Greg and Chelsea (or possibly Chelsey) are gag characters who appear in "Monster in the Garden". Their names are very similar to those of Craig and Kelsey. J.P. initially believes them to be Craig and Kelsey until he realizes that he is video chatting Craig. Both Greg and Chelsea speak in English accents. Chelsea owns a lizard colored similarly to Mortimor. They are credited only as "additional voices".
Jeff Trammell's Creeksona
Jeff Trammell's Creeksona is a background character in numerous episodes.
Tony Mozafari is a Creek Kid who is often mentioned by other Creek Kids but never seen. He is responsible for the water balloon fight in "Monster in the Garden". He spray painted his name on the Overpass, as seen in "Under the Overpass", though it is spelled "Toni". He is also mentioned in "Sour Candy Trials" and "Fort Williams".
In "The Ground Is Lava!", many Creek Kids take refuge from the lava in his treehouse.
Tony has his first somewhat significant role in "Creek Talent Extravaganza", when Craig texts him for a favor: to get the Sing-A-Long Friends to perform at the Creek Talent Show. J.P. and Kelsey begin to wonder if he is a compulsive liar, having been told respectively that he knew five astronauts and The Rock's phone number, though Kelsey called the number and was connected to someone named Dwayne. As the talent show progresses with the Sing-A-Long Friends absent, the performers play the song themselves. The morning after, looking at the refurbished Creek Daycare, Craig concedes that Tony was lying, only for the Sing-A-Long Friends to arrive, shocking the Stump Kids and ending the episode.
Tony, like many other characters, is based on one of Ben Levin's friends.
Sammy Ballou and Sarah
Sammy Ballou and Sarah were two Creek Kids who played in a fort before the original Capture the Flag War. The Creek Kids find an unsent letter from Sammy to Sarah in "The End Was Here". In "Breaking the Ice", Craig and Wildernessa discover their fort containing a calendar from the 1980s, a photo of the kids, and a drawing of them.

In "Itch to Explore", Craig mentions Lisa Kowalski, a kid who found a shopping cart in the Creek from an unrecognized grocery store called Minor locations#Herbenger's. Kelsey does not like the name, claiming she'd never shop there.
In "Itch to Explore", Craig mentions that a kid named David Brenneman fell into a hole in the Creek, which is now named "David's Folly". J.P. adds that he heard David's pants got muddy.
