Pluto is most interested in the cat herd info! The knitwear is nice and it certainly sweetens the pot, but Maes loaded her up pretty good already. But, the knitwear plus three neat bits of info from the cat herd is enough to get Sora the yearbook and the two reports!

Stuff she's most interested in knowing: how much of the town everyone has discovered (showing her the map will do), and how much contact everyone's had with Dr. Solis. Third thing is dealer's choice!

As for the long term deal... plutonium is always the quickest way to her heart, but information is also very valuable. What's this incredibly valuable thing that Sora's after?
