That was fine. Cloud was close enough to the edge for her to strike.

The flash of silver turned out to be nothing more than the undine's tail, which Cloud would have caught a glimpse of as the undine suddenly lunged forward, her soft songs turning into wicked laughs as she grasped his ankles in an attempt to drag him further into the water and down into the abyss. She pulled and pulled, trying to make Cloud fall and make the process much easier.

Despite her seemingly frail looks, the undine was remarkably strong as she grinned at Cloud, her lips lifting up to reveal rows of sharp teeth.
