同屋

同 = 冂 + 𠮛 : Tommy Turtle (tu) is stapling (冂) a magical scroll (𠮛) to the wall of the engine's kitchen ((e)ng2). On it he wrote that he's looking for two twins (mnemonic symbol for 同).

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!
