I was going to say, play with the rhythm a little... Say, like this:
Munching and crunching in the back of my mind,
Breaking up dreams and spewing some kind
Of nasty ideas, and things terribly cruel
Things that should never be allowed to rule
Dark corners, and hallways are now out of sight
And taking advantage of somebody's plight
Brewing in darkness, the things one should hate,
Waiting for someone to come take the bait,
To Then send all the horrid ble dreams that way
That To come in the dark, and eat all they may.
Yet all of the monsters, bone-crushing and vile,
Can still bring about things to make others smile.
For while during the hour when dark things roam around,
One must create lightness to brighten the sound,
To send the dark, evil things fleeing away,
Great heroes are made, with the breaking of day.
switchedà[the monsters] therefore, as cruel as they are,
though breaking up dreams and wandering far,
Aren't really so bad, since they let one create
Bright shiny new things to that can challenge that fate.
I added the parts in red, and scored the parts I think could possibly be removed…see what you think.
