[...Yeah, that's definitely Kingdra's kid. It shouldn't be much of a problem now, but-]

Just make sure to tell him if he sprays you too hard, alright? If he gets into the habit of being too rough with his water all the time, he might end up hurting someone on accident. It'll be good to teach him when it is and isn't okay to spray people, too. When wintertime comes back around, getting soaked all the time could get you really sick.
