I believe your squirrel looks fine from this angle. [ Tsunade's face is relatively focused. ] They look kinda scrawny, but they don't look malnourished. If they were sick, they wouldn't be resting so sluggishly. I think maybe just let it rest up and see what it found in you. Maybe it just thinks you can protect it, or something. [ Tsunade didn't exactly know why a pokémon would seek a human specifically but she's seen it before in the case of Tonton not going near threatening people but curling up against nicer ones. With that, Tsunade couldn't exactly make a sure hypothesis with what's going on, but he didn't look gravely ill. ]
