He takes the surprise gracefully — after hitting the water, that is. Beforehand, he flails and looks like an overgrown kid, heels bumping ineffectually against the smooth surface of the ice. It's a trick that Korra finds works well against people outside of the Water Tribes. Being told that someone's a waterbender immediately brings about thoughts of pushing that water one way or the other, but less often calls to mind the reminder that the more skilled of benders can shift water between phases, just as how firebenders can play with lightning, and earthbenders with metal or sand.

Catching the lifeguard's movement on the edge of her vision, Korra smirks and waves an arm dismissively in his direction. If Naruto ends up having any trouble with water or injury, Korra's convinced that she'd be able to take care of it faster than that lifeguard, anyway.

"I am sticking to water for your sake, but you never said it had to be liquid," Korra points out with a cheeky grin, raising another wave of water and smoothing it out into a flat, icy surface in front of her. Using it as her level, she shoots her arms across the ice, sending frozen discs hurtling in Naruto's direction. They're too brittle to seriously injure, but solid enough to sting.

"Now this, you should be familiar with!" she points out, knowing Naruto has a decent background in bladed items.
