Getting multiple MCs to move at the same time

Hiya, I have a bunch of MCs that when you click each individual one it will start to move up and down with a yoyo-ing tween. I would like all of the MCs to move up and down at the same time rather than start exactly when you click on them so they are moving at different times.
Does anyone know how to do this?
I’ve attached a sample of the MCs moving individually.
Thanks guys :slight_smile:
