[What the shit, Sampo wasn't supposed to want to keep it, and Gepard ducks his head underwater for a moment. Just a brief moment. If asked, he's prepared to lie and say that it's to keep himself hydrated. Proper hydration is important. Dry gills tend to get sensitive. He can survive out of water far longer than a human might expect, at the cost of really sensitive gills. Could be worse.

And it's technically true, though the real reason is because he had to hide the moment in which he felt flustered (slightly widened eyes, a slight smile) when his human said he'd take good care of it, because that sounded like he wasn't going to trade it to the first person, which- well. Well.

Well well. Well well well well he should say something instead of basking in feeling pleased.]

You don't have to get me anything. [...] Besides, I'm a fish. [Basically.] I'd probably ruin anything you got me just because of what I am.
