Legends of Spark Season 1 Episode 9 The Treasure Hunt

Spark messes up Hairpin's workroom. Afraid to admit his mistakes, Spark takes Bellows with him to the Duelling Racetrack, trying to find a rare ore to give to Hairpin as compensation. His reckless behaviour puts Bellows in danger, and though he saves him, Spark carelessly lets his engine fall off a cliff. Hairpin rushes there along with Faye and helps Spark to retrieve the engine.
