A wild country appears, and asks you what country he is from.
“But do not worry, my friend! The wall’s always there for you to watch, waiting for entrance into the next building, where the LNU is!”
Okay, fine. Watching the walls, you realize something important. You rush back to the country, and tell him who he is. He says, YES! Come, come, little one, wonders await you!
