Mack is the truck that transports Lightning McQueen, and was his best friend. He came with the decoration for Christmas 2010. He is voiced by the only actor who has performed in every Pixar film, John Ratzenberger. Mack is also the one who made the parties: Mack's Holiday Bash ('N' Crash), Mack's Spring Brake Party 2011, and Mack's Summer Car-B-Q. Mack's June Vroom was also a plan, but the plan was cancelled and replaced with Mack's Summer Car-B-Q.
