What are the names of the kids in the movie "Spy Kids 3D: Game Over"?

The central kids in Spy Kids 3-D: Game Over are siblings Carmen and Juni Cortez.

Carmen Cortez, played by Alexa Vega, and Juni Cortez, played by Daryl Sabara, are the franchise’s main young heroes. In this third film, Juni has retired from the OSS and works as a private investigator, while Carmen becomes trapped inside the virtual-reality video game Game Over.

Juni enters the game to rescue his older sister and stop the Toymaker, a former OSS agent who designed the game as part of a plan to control children around the world. The adventure takes the siblings through increasingly difficult game levels and brings back their teamwork, courage, and inventive spy gadgets.

The film also includes other young characters, including Gary and Gerti Giggles and the Game Over contestants Francis, Arnold, and Rez. That broader group can create confusion, but Carmen and Juni are the named sibling protagonists traditionally meant by this trivia question. The movie was released in 2003 and was presented as a 3-D adventure.
