For many years it's been a real mystery as to why we've never seen the parents of Donald Duck's nephews, and it was great to've seen and have mentionings of Della Duck for the first time in the DuckTales Reboot after it premiered in 2017. It would indeed  be nice as well if Della were also able to make appearances outside then one of these years, for instance with appearing in times that we see of Donald's good friends Mickey and Goofy.
