Baloo and Bagheera walking off into the sunset, singing "The Bare Necessities" together.
A meta example. This was the last animated film Walt Disney worked on. The ending with Mowgli being drawn into the village by the singing girl was his idea, and he had to fight tooth and nail to convince Ollie Johnston that it was the right ending. Afterwards, Hazel George (Disney's personal nurse) went up to him in tears, saying that it was perfect.
The love and care that many of the jungle animals give to defenseless Mowgli is adorable.
The 1994 live-action film
Young Mowgli and Kitty fall in love, and are reunited later in life against all odds.
