Sisters Brea and Senni Tonnika were con artists who were at the Mos Eisley Cantina at the same time as Luke Skywalker in A New Hope. Christine Hewitt played Brea Tonnika and Angela Staines played Senni Tonnika. A mugshot of one of the sisters can also be spotted in the episode “Lightsaber Lost” from The Clone Wars.
The short story “You Owe Me a Ride” by Zoraida Córdova that appeared in the anthology From a Certain Point of View was written from the point of view of the Tonnika sisters.
In Legends materials things get a bit more complicated. In Timothy Zahn’s short story “Hammertong: The Tale of the “Tonnika Sisters” that can be found in the anthology Tales from the Mos Eisley Cantina it is revealed that the two women in the Cantina are not, in fact, Brea and Senni Tonnika, but rather two other women – Shadu D’ukal and Karoly D’ulin – impersonating the Tonnika sisters.
