There's a monster that lives ‘neath your bed

Oh for crying out loud it's a futon on the floor

He must be flat as a board



There's a creature that lurks behind the door

Though I've checked there 15 times 

When I leave then he arrives

Every night



Tell the monster that lives ‘neath your bed

To go somewhere else instead

Or you'll kick him in the head



Tell the creature that lurks behind the door

If he knows what's good he won't come here no more 

Cause you'll kick in his butt at the count of four



Goodnight demon slayer, goodnight

Now it's time to close your tired eyes

There are devils to slay and dragons to ride

If they see you coming, hell they better hide



Goodnight, goodnight, goodnight

Goodnight my little slayer goodnight



Tell the monster that eats children, that you taste bad

And you're sure you'd be the worst he's ever had

If he eats you, don't you fret, just cut him open with an axe

Don't regret it, he deserved it, he's a cad



Tell the harpies that land on your bed post

That at the count of five you'll roast them alive

Tell the devil it's time you gave him his due

He should go back to hell, he should shake in his shoes

Cause the mightiest, scariest, creature is you



Goodnight demon slayer, goodnight

Now it's time to close your tired eyes

There's devils to slay and dragons to ride

If they see you coming, hell they better hide



Goodnight, goodnight, goodnight

Goodnight my little slayer goodnight



I won't tell you, there's nothing ‘neath your bed

I won't sell you, that it's all in your head

This world of ours is not as it seems

The monsters are real but they're not in your dreams

Learn what you can from the beasts you defeat, 

you'll need it for some of the people you meet



Goodnight demon slayer, goodnight

Now its time to close your tired eyes

There are devils to slay and dragons to ride

If they see you coming, hell they better hide



Goodnight, goodnight, goodnight

Goodnight my little slayer goodnight



Goodnight, goodnight, goodnight

Goodnight
