How to make a moving tail effect in UNITY 2D?

Unity

How to make a "tail" effect on a moving person in UNITY 2D? I want to do something like in the photos, but change the length and shape a little, adjust it to my game. If anything, I'm a novice game developer, and if I formulated something wrong, then I'm sorry.




PS "tail", even if the object ON THE SCREEN does not move, will be directed downwards, which will create the illusion that the circle is moving upwards. When moving an object (circle) to the right or left, the "tail" will take on the corresponding deformation. Write, if something is not clear, I will clarify ...
