The Race Against the Mammoth Car (Part 2)

Plot
Thinking that Speed and Trixie are dead at the bottom of Lake Icy Chill, the Mammoth Car drivers continue the race. Through Speed's telescanner, he sees them leave as he reaches soil. Trixie now sends a message in the homing robot to Inspector Detector. Speed strongly suspects that the stolen gold is aboard on the Mammoth Car. From his plane, Cruncher Block spots the Mach 5 back on the road. After the Mammoth Car steers off the road, Speed and Trixie follow it, as does Racer X. The Mammoth Car leads them to an oil refinery. As Speed and Trixie get out to investigate Cruncher Block's plane, some of the Mammoth Car's crew fires at them. When they escape into a mining tunnel, they jump on top of a speeding trolley car before it crashes. Back at the refueling station, Spritle and Chim Chim sneak outside of Cruncher's airplane. They escape into the tunnel, which turned out to be Cruncher's headquarters. Speed and Trixie are both tied to a trolley loaded with three tons of dynamite connected to it. Racer X arrives and saves both of them.

At the checkpoint, the Inspector searches the Mammoth Car. No gold is found there. When Speed reaches the checkpoint, Spritle and Chim Chim slip out to hide in the Mammoth Car. The Mach 5 and the Mammoth Car cross the finish line and tie for first place. They continue at breakneck speed towards the shipyard. Now, Spritle and Chim Chim both knock out the Car’s driver while Speed jumps in and then flees with his brother and chimp just as the car causes a collision with an oil tank, making it melt into a pool of molten gold.
