Animating Tail of Object

Hi Community,

I’m trying to do 2d animated ball will be used by player (not skeleton mesh), it has animated tail but I want to apply that physics.
First thing comes to my mind is, have flying straight animation, go up animation and go down animation.
But in blueprints I could change flipbook, but problem starts here its just swap at the screen, I want transition more smooth.
Any design advice would be very helpful. I hope I could explain clearly.

No one knows nothing?
