can someone twll me wat the 3 songs the rats sang meant?

Ok, so the rats. Y'know Mr B., right? Well, He's made up of the rats. So the rats formed to create the other Mr. B. The song means that they can see Coraline, and that it's like a warning sign for her. 'When we rise from underneath" I think it means when they rise from the Other Bobinsky's coat. Make sense? We are small but we are many, well, that explains itself. They were there when coraline came to the Other world, they will be there when danger arrives. We have tails (self explanatory) we have eyes, (they can see her). they were there when she left, they'll be there when she comes back to save her parents. The last one is that they have eyes and they have nerves (which could represent that they are alive, she'll get what she deserves (That's what she gets for falling in the Beldam's trap.)
