i caught a squid

My scar is from a polar bear, my curse is from a witch,
I’ve caught a giant squid in all the seven seas.
I’ve picked up rocks from distant moons astronomers will discover soon
But I would give them all back just for you.
Anything for you
All of this is true 
But the best story that I could ever tell
Is the one where I am growing old with you. [x]
