Luna's third scent, as she told Neville because he was the only one left at the end, was pudding.

Why pudding? Who knows? Luna didn't feel like she needed a reason to like the smell of pudding. She just did.

Luna loved pudding a lot. It was sweet and slimy and oh so good. The smell of pudding reminded Luna of the taste of pudding which she liked. Especially the pudding at Hogwarts. No one cooked pudding like those house elves.

And there's Luna. Next I'll either do Draco or Ginny. R&R and to all a good night.
