As Orion entered through the door, the first thing he noticed was the theme of the house from inside, and observing all of that, he felt very surprised.
From the outside, he knew the house appeared to be a spherical structure, but from the inside, it was hard to tell. As soon as he entered the door, the first thing he saw was a small hallway leading to another door not far away.
The hallway appeared normal, similar to those on Earth, with rectangular edges and walls on either side. What caught his attention was that the walls weren't painted. Instead, they were covered with grass, which initially made Orion think they were painted. Upon closer inspection, he realized the walls were actually covered with light blue grass, not paint.
He hadn't seen anything like that on Earth, so when he encountered grass used as paint, he was shocked.
