Question How to achieve this flexible animation?

Hi,

I recently played Flip Dunk by Voodoo. The game wants you to hold down on the screen in order to start flipping the character. The animation looks "elastic"/"springy".

I have recorded a video from the app where that behaviour can to be oberseved

I am relatively new to Unity and wondered how one would achieve this. Using some kind of elastic hinge joint is my only idea apart from baking the elasticity into an animation but that seems a little overdone.

I am happy for every pointer or idea you guys have!
