So, WaniKani mnemonic for this uses “MUSH” word that I had no idea about and its kind of hard for me to form mnemonic with it (non-native english speaker). So I came up with this:
Stray calf (cow kid) come to me crying. Turns out, his mom was eaten by some humans! But poor girl managed to escape! I see something unusual in this little cow. Cow has very big USHI (ВУШІ) ears. So I give this cow a name USHI and keep her as my pet!
“Вуші” (Wushi) is a weird way of saying “ears” in Ukrainian
