The Pebbles and Bamm-Bamm Show

Pebbles overhears a conversation that makes her think Fred is going to be fired, so she gets a job working for Mr. Slate at the gravel pit to make her father look good. Her interference blows a major contract for Mr. Slate and costs her father a promotion. Pebbles then sets out to find a way to save the contract -- and her father's job.
