Background notes: In the time period 1982 to 1999, when the stories with Biquinho were produced in Brazil, Biquinho was given the friend and playmate Cintia and her family as a supporting cast. In the time period, Cintia was often used in the stories, but after the production of stories with Biquinho was moved to Italy in 1999, the stories with Biquinho were changed and she and her family was dropped and haven't been used since then.
There are no records of Dona Guida being transferred to other media. Considering she only appeared in 14 stories in the time the Biquinho stories were produced in Brazil, it is highly unlikely that she has appeared in other media.
