I purchased the music box itself, a base, and various parts from the same store to create a customizable music box. The song is "Under the Sea." I haven't attached the parts because I haven't wanted to. You can attach them as shown in the fourth picture for reference, or you can create your own combinations and arrangements. You can use glue or other adhesives to attach the parts. I will also include five seashell parts, a ship, a penguin (made of glass), and a fish (made of glass). I haven't used it much, so I don't see any major scratches.
