[Whoa! Not fair! Do not throw snowballs when your enemy least expects it! (Actually, Yuffie would argue any other time that it's the best and only time you should attack, because that is the ninja way!) So, when she tries to duck out of the way of the first, only to be hit by the second, she's genuinely shocked by his technique.]

Pleh! [She spits out some of the snow that's gotten into her mouth, but she holds fast on throwing one in retaliation, for now. She's gotta give credit where it's due.] I see you're learning the ways of the ninja. Rule number one... attack when your enemy least suspects it.

[And she tosses the snowball up in the air and feigns throwing it before she grabs it in her other hand.]

Never let 'em know when it's coming.
