How does Salman Rushdie use imagery in Haroun and the Sea of Stories?

Imagery:

"Haroun often thought of his father as a Juggler, because his stories were really lots of different tales juggled together, and Rashid kept them going in a sort of dizzy whirl, and never made a mistake.

"It seemed that all Rashid had to do was to part his lips in a plump red smile and out would pop some brand-new saga, complete with sorcery, love-interest, princesses, wicked uncles, fat aunts, mustachioed gangsters in yellow check pants, heroes, fights, and half a dozen catchy, hummable tunes."
