The Original Ending:
The original "Jungle Book" was a short-story by Rudyard Kipling, a man with surprisingly little tolerance for anything resembling Disney bullshit.
His mustache would not allow it.
In Kipling's version, when Mowgli decides to return to polite society, polite society isn't so certain it wants him back. The village Mowgli tries to return to in the short story re-banishes him to the wilderness, and the family that was kind enough to take him in gets tortured as sorcerers.
In response, Mowgli recruits Hathi the Elephant for help. But the thing is, the book's Hathi isn't the cuddly, forgetful old Major of the film.
