Sheep
The sheep radical and the sheep kanji are the same in looks as well in meaning.
よう
ひつじ
None
To remember よう, we use the word "Yogurt." The sheep are after you. There are too many of them, and they're chasing you down, stalking you... because you stole their sheep's milk yogurt (よう). Now you're running and crying and trying to eat the yogurt before the sheep catch up and stomp you down with their hooves.
