When three big mail deliveries are needed around the world, there's only one monster machine who can deliver it all, Mail Truck Blaze; he'll swim across seas, climb mountains and venture to the Monster Dome, because mail trucks always deliver.
Blaze, AJ, Stripes, Starla, Zeg and Crusher take part in the big Halloween race in Axel City. Whoever makes it across the finish line first wins the biggest, tastiest prize.
