Wobbly Walking Animation help

So I’ve been wanting to start a little experimental game idea but Ive hit a huge wall before Ive even started.

Problem is:

Im trying to create a tilt marble game for mobile but instead of a marble I wanted to have a waiter struggling to keep his balance

I cant even begin to think how I would pull something like that off, maybe I should just keep at the courses? ;D

But anyway have guys got any pointers or advice in general?

Cheers <3
