Recording a tutorial on how to make a 2D animation of a goal scored.

Hello, I am looking for a person to record a tutorial on how I can make 2D animations of scored goals like this one: https://youtu.be/zPpsbPwOoDY?feature=shared

It was made by a guy from reddit and below is the link where he describes in the first comment (nickname: rjtavares) how he does it, but I can't understand it and I'm looking for a person to explain it to me in the form of a tutorial. Rate to be negotiated.
