What is the authors purpose in describing the boys attitude towards Arabs and spainards?

Huck tells of one of Tom's games involving a caravan of Arabs and Spaniards was going to camp nearby with hundreds of camels and elephants. This adds an exotic element of a boy's (Tom's) imagination. Tom also alludes to Cervantes’s Don Quixote. Much like Cervantes satirizes society and human nature in Don Quixote, Twain gives Huckleberry Finn the its own imagination and societal criticisms. Huck is a Don Quixote embarking on a journey of adventure, truth and the absurd.
