What is the name of the Pixar short-film series featuring Mater telling exaggerated stories?

Mater’s Tall Tales is the Pixar short-film series featuring Mater telling exaggerated stories.

The series is part of Cars Toons and centers on Tow Mater’s outrageous accounts of his supposed past adventures. Each story often places Mater alongside Lightning McQueen in a different genre or situation, such as firefighting, wrestling, or espionage. The humor comes from Mater’s confidence and the question of whether his stories are true.

The shorts use a framing device in which Mater tells the tale, while events are presented from his point of view. This lets the series parody familiar action and adventure formats without changing the main continuity of the Cars films in a conventional way.

Mater’s Tall Tales should not be confused with the feature film Cars 2, even though that film also uses an international spy premise. The shorts were released as individual animated segments and later collected under the Cars Toons name.
