What is the name of the short film in which Mater encounters a ghostlight in Radiator Springs?

Mater and the Ghostlight is the short film in which Mater encounters a ghostlight in Radiator Springs.

The short was released in 2006 as a companion to Cars and focuses on Mater's habit of frightening the other residents with tall tales and practical jokes. The town's characters respond by telling him about a mysterious blue ghostlight that supposedly haunts Radiator Springs.

Mater becomes frightened when the light appears, but the story eventually reveals that the residents staged the event to teach him a lesson. The short blends local folklore with the playful comedy associated with Mater.

Mater and the Ghostlight is not one of the Cars feature films and is not the same as Cars Toons: Mater's Tall Tales. Its title specifically refers to the ghostlight story, making it distinct from the later series of short adventures.
