The series debuts some fully realized Ithorian and Quarren models in this episode. Previously, the Star Wars: The Clone Wars (2008) movie used cobbled together figures to represent these background aliens. In Jabba's palace, the Ithorians were made of a crudely modeled head stuck on Palpatine's body, and the Quarren was a simple head stuck on Obi-Wan's body.
The city of Cliffhold on the moon of Iego is based on concept art designed by Doug Chiang for Star Wars: Episode I - The Phantom Menace (1999). In that movie, Anakin also mentioned 'angels' living on the moons of Iego.
The city of Cliffhold is based on old Doug Chiang designs from Star Wars: Episode I - The Phantom Menace (1999). It is filled with Aurebesh graffiti, including incidents of Jaybo Hood's name scrawled on the walls or simple illustrations depicting droids and clones. One building is marked with a large Aurebesh marquee that reads "Kristal Skull" while others translate as "Iego City Hall", "Clone" and "Battle Droid" .
Iego is a nod to Lego, the popular line of construction toys. In 1999, The Lego Group released "Lego Star Wars" play sets of the original trilogy, the prequel trilogy and The Clone Wars.
For the Dutch dub, the name of the Ghost of Drol was changed to 'Grol', because 'drol' means 'turd' in Dutch.
