Trick or treat / Halloween limerick

Children are out for 'trick or treat'
Wanted dollars for their own greet.
They would go to canteen,
on next day of Halloween,
buy sweet pastries, they would eat.

Came to my door, three horrible ghosts.
Looking on them, I was scared almost.
To bring treat, I went in.
On return, were not seen.
The ghost were hiding, behind the post.

Three little girls, were out in a team.
To have full bag candies, was their dream.
They knocked, the old man's door.
A ghost came and did roar.
They ran away with very big scream.

I have observed, mostly my dustbin,

happy and cheerful on Halloween.

Because fills it's tummy,
thing it finds most yummy. 
That's fresh skin and pulp of pumpkin.
