Kintrot Cuckoo Clock Black Forest Quartz Wall Clock Pendulum Movable Bird, Dancers, Watermill, Wood Chopper

What do you have to do to make the pendulum work?

How many melodies does this clock play??? it says 12 in the details but when asked by another customer it only lists "happy new year" which is it???

Do you need to move the weights?

In the details it says it play's 12 songs is that right? the answer for the same question below only lists "happy new day" which is it???? 1 or 12
