Sandburg's use of literary techniques such as onomatopoeia, alliteration, repetition, and nonsense words makes the story playful and cheerful.
The onomatopoeic words in the story enhance the reader's imagination of the events:
Then the blue foxes and the yellow flongboos pattered pitty-pat, pitty-pat, each with feet and toenails, ears and hair, everything except tails, pattered scritch scratch over the stone floors out into the train shed.
Alliteration and repetition make the story musical and rhythmic, giving it a captivating quality:
And there on a high stool in a high tower on a high hill sits the Head Spotter of the Weather Makers . . . A big wind blew up and blew and blew till all the tails of the animals blew off.
The author also uses nonsense words such as flongboo, parleyhoo, and flangwayers. These words make the story fascinating and engaging for children, who can use their imaginations to understand what these words represent. For example, a reader might try to imagine what a "flongboo" or a "flangwayer" looks like:
It is hard for the yellow flongboo to lose his tail because it lights up his way when he sneaks at night on the prairie, sneaking up on the flangwayers, the hippers and hangjasts, so good to eat.
These nonsense words also provide a comedic touch to the story:
The animals picked a committee of representatives to represent them in a parleyhoo to see what steps could be taken by talking to do something.
