Mookie was a male doll that belonged to Kata Akuna; her mother had gifted it to her. She used he/him pronouns when speaking of the doll. The doll featured purple horns, orange highlights, and a turquoise-colored body. As Kata prepared to depart the II-0810 Satellite Station, her home while her father, Bode Akuna, was working for the Imperial Security Bureau, she worried that Mookie was missing; however, the Jedi Knight Cal Kestis located the doll underneath a holotable. Kata kept the doll with her until her father's death on Tanalorr. She placed Mookie on top of Bode's corpse as it was burned on a funeral pyre.
