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.
