If DisneyToons made a Latt 3 what would be the plot?

エンジェル and Scamp would have 赤ちゃん and one would probably be discontent with his/her life and run off to be a 通り, ストリート dog. I don't really see much else that can be done with these movies. または maybe a prequel film telling もっと見る about エンジェル または Tramp's past.
