Game object follow path of other game object

I want to create game object such that it follow path of other game object. If first object moves in curve path then second object follow that path also.

Thats it I want to implement only this thing, At present I can’t able to figure out what to do?

UNITY have no path,but there are some plugin to do,such as:
or this:

You can use GoKit to achieve that having both objects follow the same path: GitHub - prime31/GoKit: Lightweight tween library for Unity

You can create the path dynamically or using the included editor
