They are first mentioned by Kiara, as the young princess explains to her friends, Tiifu and Zuri, that they were waiting for her to announce the start of The Royal Buffalo Wallow, and she doesn't want to be late for her royal duty.
When Kiara finally arrives, she greets Vuruga Vuruga and, after a bit of small talk, she announces the start of the Wallow. She and Vuruga Vuruga watch as the herd takes part in the event, where they wallow about in the mud with great joy.
Vuruga Vuruga's herd graze at night, until Fuli approaches them, ordering them to move. But since the cheetah has been painted for the Ukumbusho, none of the buffalo recognize her. With time of the essence, Fuli pretends to be a monster that comes out during a full moon to eat buffalo, and suggests that they run. After some more snarling, the herd become frightened and leave.
Vuruga Vuruga serves as the leader of the herd. She is gracious to Kiara and is also very understanding. She appreciates an appropriate appearance. However, she is not above malice, as seen when siding with Twiga to set up Makuu. But she is also capable of forgiving those that she believes to have wronged her or her friends.
