Can You Guess

Home! Home! Is where I'd rather be. Deep in the inner parts of the earth is where You will find me. I am a magical fellow who is about five inches Tall Moving through solid earth as if it were nothing At all. As far as predicting the weather I've never Made a bad call. One more thing. I can smell way better than Any thing that can see. They say it must have some thing to do with my Chromosomes. Did you guess what I am? Aw! Shucks folks. I Am a Gnome.
