How do the words poof and fwump add to the story?

They are sound effects, also know as onomatopeia

Explanation:

If you say these words, you can relate them with sounds that you've probably heard before.

Using words like this in stories can add real immersion with giving actions 'sound' and a real take on how something is one, example being if something is done with lack of force it would just 'thud', but if someone dropped something heavy with a lot of force it might be given the word 'WHAMP' to characterize a lot of force hitting the ground.

Explanation:

These words are onomatopoeias, meaning they're words that give actions 'noise', but they aren't quite verbs. These are commonly used in comic books or in animated television shows.
