What's This Thing In My Bed?

What's this thing in my bed
Under the sheet?
It jumped on my leg
As I started to sleep.

It's skinny and long
With fur on each end,
And it's shell is quite hard,
It surely won't bend.

I don't want to look,
I am really quite scared.
I don't want to move
Until it's ensnared.

Oh, what shall I do
And where shall I go?
So I grabbed my left shoe
And dealt it a blow.

I turned on the light
And gazed at the bed.
Thank goodness, I'm saved!
The Q-tip is dead!
