Shake
Wave
You're trying to use your fingers to cause a landslide so you have to shake the earth. You probably won't succeed, but the best you can do is to shake your hands on the dirt as hard as you can. It looks like you're trying to wave at the ground now.
しん
ふ
None
You think you finally got the earth to shake but when you look down it's just your shins (しん). Darn you shins, I thought I made some progress. Hey wait... why won't you stop?!
