There are two ways of doing it

The super fast and easy way would be for you to make a Hobby: puppets and then take weapon levels and maybe give the puppets some perks or just use your power moves for the puppets doing cool things.

However if you wanted to have it stats we can just do it like the example characters of Karis and her ro-bro; use the servant ability for the puppet and maybe have your puppet skill act as the attack roll
