This is a music box that Twister has had since she was very young, but she doesn't show it to anyone afraid that it would break

Here's a better look at the center piece

And here are Lyrics of a the song it plays

When the light shines
Down on Earth
Just know that I am here
No matter where I am
I will always be your friend
Even on the scary nights
Or the darkest days
The light will shine through to you
So just keep smiling
And just laughing
Don't be afraid...
Everything's OK
Everything's OK
Everything's OK
