I've got a bug inside and it is just a little housefly
I got a bug inside it tickles like a butterfly
I've got a worm that's mine and crawls around my whole inside
And when I dont feel right it feels just like a parasite

A bug, get it!
A bug, kill it!

And you will never know how it feels to light up the sky
And you will never know how it feels to be a firefly

My body is a jar for a special insect caught inside it
Sometimes it lights me up but I would never let you know it
Sometimes it crawls around and makes me laugh when I am down
I dont wanna let it out yet I am greedy little bug

A bug, kill it!
A bug, get it!

And you will never know how it feels to light up the sky
And you will never know how it feels to be a firefly

Sometimes I look for a safe place to keep my little bug
Sometimes it flutters around trapped and I feel so sad
But I know what would happen if I ever let go of it
I think that this cruel world would surely kill it

A bug, kill it!
A bug, get it!

And you will never know how it feels to light up the sky
And you will never know how it feels to be a firefly
And you will never know how it feels to light up the night
And you will never know how it feels to be a firefly
