Inigo hums too, but definitely shorter than Tidus just did. As if this is something he doesn't really has to think about, and is more pretending to do so for appearance's sake.

"That dancing arcade machine would be a lot of fun.."

Even with how much trouble Inigo has with buying stuff for himself. M-Maybe it's okay since it means other people could play on it too..?

Or maybe he immediately has to say something else that's less selfish to make up for it, like: "Maybe I could see if there's something big that'd be good for those kids who are so interested in art.. you know, while the train still hasn't added an art car for them." And since Tidus seemed so concerned about it for their sakes.
