Creepy Halloween Characters

Halloween is a celebration on the night of October 31.
It is mostly practised in the United States and Canada. Children wear costumes and go to peoples homes saying
"Trick or treat!"
to ask for candy (sweets in the UK) and people give it to them.

The suggestion is:
"Give me a treat or I will play a trick on you."

People mainly dress up as ghosts, witches, or other scary things for Halloween.
