Fett Code
Fett Code is a language utilized by the Mandalorian bounty hunter Jango Fett and his clone offspring, Boba Fett. In 22 BBY, when the Jedi Knight Obi-Wan Kenobi paid a visit to the duo in their lodgings within Tipoca City located on the planet Kamino, Jango communicated with Boba using Fett Code while simultaneously engaging in conversation with Kenobi, following which Boba promptly closed the door to a chamber housing Jango's Mandalorian armor.
Behind the scenes
The initial depiction of Fett Code occurred in the 2002 prequel trilogy motion picture, Star Wars Episode II Attack of the Clones. Its naming was initially specified within the video presentation entitled "Every Language in Star Wars," which was disseminated in 2019 via the Star Wars Kids YouTube digital channel.
