Auto Body Parts - Express Edition by Michael Dahl

Aboard a strange-looking bus, a girl hears whining coming from a hatch beneath her seat. The whines sound like calls for help. When the girl lifts the hatch to investigate, a hand reaches out and grabs her leg. Then another hand grabs her and another! Are the body parts reaching for help . . . or do they want something more?
