Doctor Finklestein lives in a large observatory with his living rag doll creation Sally[14] and his hunchbacked assistant Igor.
Finklestein acts as an over-protective father and in some ways an overbearing husband towards Sally by keeping her under lock and key under the pretext of sheltering her from the world. In addition to being an overbearing and antagonistic father figure for Sally to overcome, Finklestein also has a hand in helping Jack Skellington with his plan to take over Christmas by bringing to life several skeletal reindeer to pull Jack’s sleigh.
