How would i reproduce "Animal Revolt Battle Simulator" style combat?

Ive been trying to figure this out for the last week, my first idea was procedural animation with control rig but there is literally no tutorials online so decided it was way out of my depth. So i then tried physical animation on top of modifying bones through blueprints in the animBP but i cant seem to figure out how to do it properly, the furthest ive gotten is getting the heads to look at the closest part of enemies body, but what id really like to do is modify the whole body in a way so when attacking it will lunge forward and bite with semi-realistic movement. Here is the gameplay trailer of what im trying to accomplish (the creatures specifically) Animal Revolt Battle Simulator Gameplay Trailer 2020 - YouTube
