The voice (Shelby Flint) singing the somber songs in this movie, is either Penny's singing voice, or what her singing voice will sound like when she gets older.
Cody from The Rescuers Down Under is Cody Martin
Cody's father was a ranger.Even for a young, impressionable, naive kid who has the whole Australian outback as his playground, Cody seems very attached to and concerned about the animals, and he is constantly throwing the threat of the rangers in MacLeach's face; this suggests at the very least that Cody has either been taught by his mother or teachers a great respect for rangers, or he's seen them in action. If his father was a ranger, though, this would explain Cody's feelings and loyalty in a more personal manner, particularly if his father was killed by one of the poachers he was hunting down. (No, not necessarily MacLeach, who might have recognized Cody or who might have recognized him, though it could have been.) This could also explain the mysterious ability Cody has to talk to animals (assuming it isn't some special talent only children have), if it's a talent rangers have and Cody inherited it.
Cody's mother is actually her stepmother.Considering he has an American accent, he was actually born and raised in America, while moving to Australia with his biological dad.
The star of faith was actually Penny's birth mother (and/or father, but it would seem more likely to be her mother) giving her signals of hope or comfort from Heaven.
There actually is a mouse United Nations, the Rescue Aid Society just uses the same room for it's meetings.It would make more sense, after all why would saving troubled humans be such a high priority for mice as a whole?
Of course Kyubey contracted with Penny at one point.Or at least in another timeline. Her Witch form might be Albertine. Albertine's imagery suggests that she was young, and perhaps rather lonely. Plus Albertine obviously liked drawing, and one scene prominently showed a drawing of Penny with parents. Cody should thank his lucky stars he managed to escape...
