Need help with player interact animation with obstacles in a endless runner like zombie tsunami

Hello guys! First of all, sorry by my poorly english. I'll try to make myself the most clear as possible.

My team are now developing a 2D Endless Runner that is a hybrid of Zombie Tsunami and Banana Kong. I work mainly with illustration and graphic design at this project but always as possible, I'm been trying to help our programmer in the feature enhancement.

If you dont know zombie tsunami, take a look in this video. https://www.youtube.com/watch?v=5sri18k120c

When you have the necessary amount of zombies to overcome an obstacle like at 1:20 in the video, your horde presses the obstacle (the car) in a way that starts to angle until it breaks.

You guys know how can this kind of interaction be made ?

Sorry if it is a kind of so basic question, and for my lack of knowledge but I can't find anything about it yet :(

I'll be very thankfull with your help!
