At midnight in a cemetery, the GRX racecar engine is unearthed. The following day Spritle and Chim are trapped inside a truck. It takes them to Oriana Flub's house, where Chim Chim is tied to a motorized go-cart. When the chimp comes to a stop, one of Oriana's men sprays a "formula" at him. As he takes off again, Oriana announces that "they'll win the Grand Prix of the Orient."

At the track, a new racecar comes on the scene. Pops recognizes the sound of its engine. High in the stands, Oriana and her right-hand man, Omar watch while a thug sprays the driver of the mysterious car with the formula.

Oriana knocks him out with "sleeper gas."
