School Bus Rhonda first appeared in the episode Indie Road Rager where she was competing in the Indie 400. In this race, Trina tore the stop sign off of her bus before the race began and she blamed it on Grojband. This made Rhonda so angry, that she decided to destroy the band for what they did. In the race, she revealed that her bus was equipped with a bunch of weapons such as missiles and electric blades. She tried firing missiles at the band but kept missing and destroying other people in the race. She also activated an electric spinning blade that came out of the side of her bus. She drove sideways toward the Grojcar and attempted to slice it in half, but then the band stopped the car which got them out of the way and instead, she chainsawed the truck of Ice Cream Tom in half. Ice Cream Tom threw sprinkles at her face before he died which blinded her and made her wildly spin out of control destroying everything. At the end of the race, School Bus Rhonda fell of the track and her bus exploded. It was also revealed that there were six little kids riding in her bus the whole time.
Despite her death in the episode Indie Road Rager, School Bus Rhonda appeared again in the episode Line of Credit in a picture of Ms. Obedience kicking her on the side of the road while she was doing her job as a crossing guard.
She made a cameo again in the episode Ahead of our own Tone where she was one of the many people seen waiting in line to buy the new Blab Tap In-Brain Implant.
Rhonda is a fat woman who has short brown hair and glasses. She wears a red pladd shirt and yellow pants.
