Official bio
The first time that Tiny Lugsworth heard the term "crash and burn" he knew it was his goal to eliminate the "and burn" from that phrase. He is always ready with his eyes scanning the racetrack for any danger. At the end of the day, no racer is going to burn up on his watch. Fire trucks always have a lot of stories, but he will never forget the time when he showed up on the scene of Lightning McQueen's big crash. Tiny never expected to see one of his favorite racers go up in flames.[1]
