A Martian Halloween

Someone is screaming
and crying out moans
and the wind blows so hard
it is chilling my bones.

Now I hear footsteps
following me,
but I can't turn around,
who could it be?

I'll try to walk faster;
maybe it'll go away,
but I had heard this
could happen on Halloween day.

What ever it is
I can hear it crunching,
it might be an earthling;
this monster is munching.
