The Littlest Zombie

Three small travelers, each attired in a different disguise
observe the  lambent candlelight filling the pumpkin’s eyes.
Its outside is a Jack-o-Lantern, while all its insides 
were scooped out for the candle, and then turned into pies.

A lurching small cadaver reaches out a hand,
intent on trick-and-treating, though he can barely stand.
He’s had a whiff of candy, which has made him come alive.
He’s seen the tiny Hershey bars. He hopes they’ll give him five!

Leaving, he now remembers to walk with legs unbent.
He breathes hard through his mask where his sister cut a vent.
He imitates the groans and huffs of the walking dead,
though if he’d had his druthers, he’d have been a dog instead.

But brother said a dog just barks and never moans and groans
and that barking trick-or-treaters are only given bones!
And so he screws his face up and puffs on down the block,
scaring all the littler kids with his zombie walk! 

Prompt words for today are whiff, imitate, cadaver, lambent and candy and also for OctPoWriMo.
