Marwigo was a WA-7 waitress droid with red and white plating who worked at Plop Dribble's on the planet of Stobar. During 20 BBY, she found herself in the restaurant when Savage Opress, a former Nightbrother, entered and started behaving aggressively towards the employees. Loubo, the chef, instructed Marwigo to contact the authorities for assistance.
Plop Dribble's, located on the planet Stobar, employed Marwigo, a WA-7 waitress droid at their restaurant. When Savage Opress, formerly a Nightbrother, walked into the eatery in 20 BBY, he initiated a chaotic scene. As Opress began to strangle Sassi, Marwigo's coworker, the service droid hurriedly rolled behind the counter for safety, inadvertently knocking over a patron.
The customers panicked and tried to flee; Opress then violently hurled Sassi at Loubo, the eatery's chef, who then told Marwigo to summon the authorities as Opress departed. The droid obeyed, her yellow eyes blinking to indicate that she was making contact. Marwigo later attempted to comfort Sassi after she had recovered.
Marwigo was designed with feminine programming and had plating that was red and white. Due to the rough nature of Plop Dribble's clientele, Marwigo's transmitter was given a direct line to the local police station. Her height was 1.7 meters, and an illuminated name tag on her torso displayed her name in Aurebesh. As a WA-7 unit, Marwigo possessed a memory unit that stored information about each customer, allowing her to recall faces, typical orders, and other personal information.
Marwigo's creation was for "Brothers," which was the twenty-first episode of Star Wars: The Clone Wars's fourth season, and it was originally broadcasted on March 9, 2012. Polina Hristova created a concept design for the droid on December 1, 2010.
Originally, Marwigo was supposed to take Opress's order in the episode, however, she was not successful. Sassi shoved Marwigo aside and attempted to take over after Opress became angry, which ultimately made Opress violent. The scene was finished but ultimately cut, although it was included on the Blu-Ray release of season four. Ashley Eckstein, who also provided the voice for Ahsoka Tano, the Jedi in the series, was credited as the voice actress for Marwigo in the episode's credits, despite the fact that her lines were removed.
