See that crazed look in the general's eyes? No gas for 100 miles?! Not to worry. The general has an insane plan: using live grenades as fuel! Collect stars as you make the 100-mile trek through the jungle to the nearest gas station, avoiding any prehistoric dinosaurs roaming around. Get the jeep to the checkered flag before time's up to complete each level.
