[y-] Yoshi is in the [3] basement of the [-ang] chapel where he is preparing a bunch of 羊 sheep for a holy sacrifice. He goes up to each of them with a device that sucks all of the 氧 oxygen 气 gas out of their body, making them pass out. It is well known that the one 气 gas that 羊 sheep cannot live without is 氧 oxygen! Yoshi stores the extracted 氧 oxygen into his green spotted eggs.
