This is an altered version of a riddle. The common version of the riddle is:

> I am not alive, but I grow; I don't have lungs, but I need air; I don't have a mouth, but water kills me. What am I?

The answer to this common version is that you are fire.

It could be fire, shouldn't it needed water to live. Otherwise, the answer is that you are an underwater bubble, since it's not alive but grows, don't have lungs but they're filled with air and do need water to live.

Oh, I see. That’s a clever answer. I like riddles. They are fun and challenging. Do you have another one for me?
