"Hulk make big splash! Kenzi wet!" Hulk laughed, and jumped up and down a few times that sent mini waves out to the edges of the pond. He was happy that she wanted to play with him. He knew he had to be gentle with her, like he was with Natasha. He made some more splashes her direction, but kept them from being as big as when he leapt across the lake.
He looked at the water, then at her. "Kenzi swim?" The fact that it was freezing meant little to Hulk, he was comfortable in a wide range of temperatures.
