Although it was released in the UK as Come Play with Me 3, it is not a sequel to either Come Play with Me (1977) or Come Play with Me 2 (1980).
In the English dubbed version, the names of the roles are different. For example, Julchen and Jettchen are Jenny and Juliet, the teacher Mme Blanche is Miss Brown and others have different names, e.g. Lois.
