Out of all of his skills, his chakra control is the one most improved over his years. He'd had a hard time originally with any number of jutsu, simply because he wanted to pump too much into an intricate spell. He's learned; learned it was a weakness and made constant effort to avert the problem.

Walking on water is easy as balls. Provided he actually lands on water.

What he's expecting to be the smooth, even surface of the pool is instead a steady rush, like a conveyor belt. And below that, there's an even more unexpected layer of ice. Even as his feet pedal uselessly for grip and balance, he chastises himself a little for not realizing that one. Idiot, Kurama offers, ever helpfully. You fell for the same terrain issue again.

His tailbone hits the ice hard, sending a loud crackle through the echoing natatorium, before Naruto slips backward into the water.

He comes back up gasping for breath, and looking very much like a surprised and soaked tomcat as he crawls back out and onto the surface. The lifeguard stands, worried, but Naruto tosses him a thumbs-up over his shoulder, and the man decides to sit back down, expression still confused.

"I'm gonna fall for that one more time," he decides, wiping his still grinning face off with the back of an arm. "Third is the charm, after all."
