I was one of the animators for cinematics done by Cinematico.
The shots are broken up between standard character animation and fake 3d puppets.
I was tasked with proving the puppet concept and setting a standard for the other animators on the team to follow. There are no simulations, and everything is hand keyed. These were meant to feel like a rickety presentation being done by people who really didn't know what they were doing. They purposely make a lot of mistakes and the sets fall apart in accidental ways. It was actually a total blast to work on!
