How to add shear/wind effect on character

Hello,

I have a ghost as the main character of my game and I wanted to know how I can make the bottom move (2d side scroller by the way) like there’s a wind effect, even though it’s a singular sprite.

Just to be extra clear, what I mean is that I want the effect when the character touches a plant, the top kinda moves a little but the bottom stays still. I basically just want this upside down so that the bottom of the ghost moves while the top doesn’t, kinda like the shear effect in the UMGS. I just don’t know how to do this, with or without materials since its one sprite without bones (2d).

I really don’t want to manually animate the ghost haha.

Thank you in advance.

I still haven’t found a way to do this yet, any help would be greatly appreciated :))
