Go into Find Mii (not II), since that's where you get the accomplishment (so no, green slimes can't help you here), and have the yellow Mii cast Sandstorm and have the other Miis just attack. Eventually, one will miss three times.
Easy. Actually, any Find Mii accomplishment is easy just by hiring the guys you need in Find Mii II first.
... I think you miss the point.
The point is not to work to get that achievement.
It's to happen to get it after an otherwise frustrating event. When it happens, you are frustrated, even maybe angry, but when you see this pop up, you can't keep from laughing/smiling, asking yourself: "Really? There is an achievement for THAT! xD"
