I'm on the fence with common sense (lol that rhymes), because I feel like there are some moments in the movie where she is very sensible and other moments where she seems to lack common sense altogether! Maybe it had something to do with which writers were in charge of which scenes, I don't know. Basically, I feel like the writers had some sort of disagreement about how sensible she was supposed to be. XD

I think this one suits her though. She just seems fascinated with the world around her (especially nature) and is shown enjoying her experience living with the dwarfs and having fun with them during the party scene. She likes new experiences.
