Black, brown, tan, and white
Bhati most likely lived during Mufasa's reign. She met and befriended Nala when the latter was a cub and presumably met Simba through her.
During early production of the film, Bhati was intended to be a childhood friend of Simba and Nala's. Beyond this, her role in the film is somewhat obscured, though it can be safely said that she was an active participant in Simba's impulsive antics and loved being around her friends, as indicated by her numerous concepts.
Personality and traits
Not much is known about Bhati's personality. However, according to Mouse Under Glass, she is a "wisecracking" friend of Simba and Nala's. It can be assumed that she was better friends with Nala than Simba, as she was a member of Nala's gang rather than Simba's, which at the time consisted of only Timon and Harold.
