Review of The Jungle Book: Mowgli's Story

I loved this movie as a little kid. I was about 7 years old when it came out on VHS. I did see some characters were missing in the movie and some stuff didn't make sense. I didn't see Kaa. 1. I was asking why wasn't Kaa in this movie? 2.Since when did Mowgli have a wolf sister (instead of a wolf brother)? 3. How was Mowgli the adopted son of the wolf-leader Akela? 4. How come they only had a 7 year old kid lost in the jungle being taken in by wolves and he is still wearing clothes-the next scene his pants are torn (which look like shorts), he carries some kind of knapsack-the other scene he still wears the same pants he wore when he was in the human camp and vest but doesn't wear the shirt (still wears the satchel). That one scene when Mowgli grows a little older, the part when he swings on a vine and sees a human who is in a military uniform (and he narrates he wondered about his past). Then after running away for blaming himself about his mother's death he gets curious when he sees a human camp with real pack of man. Wouldn't a 7 year old kid if they grow up in nature around 11-12 years know about their human past? :/ 5. When Mowgli is lured by the chimps they call it "monkey-town." Looks more like a zoo place instead of being in a ruined city. What was with that abandoned hut full of old things? Who lived in that place?
