Travel Music

HI time messenger：
My dad brought me a music box carrying a Dutch windmill from Netherlands on my 8th birthday. It is very precious for me because it accompanied me for countless nights instead of my dad . Time flies, the windmill couldn’t spin anymore and my dad also gets old. I hope it could work again and then bring us back to those woderful days.
 
Every music box is a symbol of the happy memories.
And you are a time tracer, you can help them regain those beautiful memories.

Play every song,get jigsaw pieces to help me repair the music box.
