Bonita Bevel is the mother of Billy Bevel and Binky Bevel. She is the wife of Baxter Bevel. She is also very close friends with the Polie family. She was voiced by Ellen Ray Hennessy. She is one of the three pentagonists of Rolie Polie Olie, and one of the tritagonists of The Great Defender of Fun and The Baby Bot Chase.
Bonita is a square bot woman, she has tall black hair with hair clips in it. She wears a black and white striped shirt and a red vest that exposes her tummy.
- Bonita's name means "beautiful" in Spanish.
- In TBBC, she and her family (along with Gizmo Polie) are going to help the Polie family return the babies home. But the film demotes them to extra, making them supporting characters.
