I like this movie, but I think they messed up the origins of this movie, when Tod and Copper became enemies and Tod said Goodbye to Widow.
1.What if Copper decides to live with Tod and the Hunter kept Chief and when Tod and Copper grows up they explored the forest and Tod met Vixey and Vixey met Copper and they both spend one night in the forest. Them the Hunter and Chief came back and began to hunt in the forest. And Copper and Tod began to fight them and then the bear appeared and Tod and Copper saved Chief and after wards Chief protected Copper and Tod. At the end Tod and Copper returned home and they introduced Vixey to Widow.
2.Or What if at the end of the movie Tod returns home with Vixey and they both became Domestic Foxes together.
