Faline is a white tailed deer and the mate of Bambi.
She's a rather cheerful young fawn, the daughter of a friend of Bambi's mother. Once adult, she will become the mate of Bambi and she will give him two fawns, Geno and Gurri (names from the book).
In Bambi II, it's clear that she likes Bambi and he's sometimes embarassed around her. Another older fawn had noticed her, Ronno, but she doesn't like him, as he acts like a bully. At the end of the movie, she still has her patches, unlike Bambi and she and the Young Prince share a kiss, thanks also to the Porcupine and their friends.
