屋宇

屋 = 尸 + 至 : Willy Walrus lives in the space station, but sometimes he goes out into his small garden shack. Today, something is just wrong, and when he visits the shack's arrival part, he knows why: A ghost has arrived!

宇 = 于 + 宀 : Yu the Great (yu) just earned her PhD in the space station (Ø3) and is proudly putting on her graduation cap (宀). She was measuring cosmic (宇) rays by investigating the traces they left in a honey jar (于) and is demonstrating her experiment for the camera.
