Monsters and giants

What's that? What's that? What's that in the closet?
It's green, it's huge and it's scary
Oh no!
It's a monster!
What's that? What's that? What's that in the basement?
It's brown, it has fangs and it's hairy.
Oh no!
It's a giant!
What's that? What's that? What's that in the guitar?
It's small, it stinks and it's ugly.
Oh no!
It's a musical monster.
Be careful-watch out.
Be careful-watch out.
Monsters and giants are hiding all about!
What's that? What's that? What's that in your shoe?
It's white, it's sharp and it's gross.
Oh no!
It's a toenail?
