Kisame is slightly surprised at the gift of the fish, but if the kid is going to give it to him, he won't waste the catch. One of his summons is especially fond of flounder. So he signs 'hold still.'

A moment later a flick of his thumb across his thumb spills blood into the water, and he summons. The shark is small, for a tiger shark, and swims around Kisame in happy circles, happy to have been summoned. Kisame's smile goes a little more fond than his usual grins which promise violence, and he pets the shark along the nose and gills, making her wriggle in pleasure.

Then he uses the Hoshigaki signs to tell her that the kid got her a present, and not to take the kid's hands off in the process.

With that, the shark is swimming straight towards Naoki very fast, mouth open and teeth gleaming.
