A little pool with two layers of wall around it. One white and soft and the other dark and hard. Amidst a light brown grassy lawn with an outline of a green grass.

When Iām metal or wood, I help you get home. When Iām flesh and Iām blood, In the darkness I roam.
My first is in window but not in pane. My second's in road but not in lane. My third is in oval but not in round. My fourth is in hearing but not in sound. My whole is known as a sign of peace. And from noah's ark won quick release.
I'm the source of all emotion but I'm caged in a white prison.
