Mater is working as a fire truck and has to rescue Lightning McQueen from a burning building. After he saves McQueen, the ambulance rushes McQueen to the hospital where Mater reveals that he's also a doctor (with an MD, PhD, STP and GTO).

Mater is a daredevil, dressing in a style like that of Evel Knievel. In a stadium, Mater attempts to jump a long line of cars, but instead merely tiptoes over them. He performs other stunts, and later claims Lightning McQueen failed to jump over Carburetor Canyon while strapped to a rocket.

Mater is a matador fighting a herd of bulldozers in Spain. When Lightning McQueen enters the story, the bulldozers chase after him due to his red paint job.
