When Dusty learns that his engine is damaged and he may never race again, he joins a forest fire and rescue unit to be trained as a firefighter, or else his air strip will be shut down.

Blade Ranger: It takes a special kind of plane to become a firefighter.
Lil' Dipper: [after Dusty is introduced to the team] Dusty Crophopper? The air racer? I'm Dipper, your biggest fan!
[pause]
Lil' Dipper: You're smaller than I thought.
Dusty Crophopper: Umm...
Lil' Dipper: But that's okay!
Dusty Crophopper: So it's... Dipper? Miss?
Lil' Dipper: Yep. Miss.
Dusty Crophopper: Dipper.
Lil' Dipper: Dipper. Yeah. RAWR!
Dusty Crophopper: [after Windlifter tells his story about Coyote] You had me up to the point where he eats his own tires.
