Snow White's innocence, kindness, and purity is very heartwarming. She doesn't say an unkind word to anyone, asks that the Dwarfs be blessed for being so kind to her, and cleans house and cooks for them simply because it's the polite thing to do. And her friendship with the animals pays off when they lead the Dwarfs to rescue her.
An unsung lesson the film teaches is tolerance. The movie was made in the 1930s and set even earlier, but not once is Snow White prejudiced or frightened of the Dwarfs. She treats them as men and equals, and asks that they be blessed for being kind to her in return.
"Some day, my prince will come, Some day, we'll meet again." And by golly, he did.
The part where Snow White helps the little blue bird.
Also when the animals meet a crying Snow White, after she was terrified of the creepy forest.
The fact that, of all the dwarfs, it's Grumpy that leads the charge to avenge Snow White against the Queen.
Grumpy turns out to be very affectionate with Snow, and it's beautiful.
The huntsman deserves a heartwarming moment. He's put in a position where he must either kill Snow White or face execution. He makes sure that her back is turned because he doesn't want to look her in the eyes. To top it off when she catches him trying the second he looks at her scared face he drops the knife and begins sobbing begging for her forgiveness, warning her that the Queen is out to get her and telling her to run for it.
The scene when Snow White and the dwarfs are sleeping, and a fly lands on one of the dwarfs and sleeps with them with a buzzing snore. It's so cute, it may be coupled with a Funny Moment.
Snow White is seen making a pie for Grumpy right before the Queen shows up.
After the Prince kisses Snow White, he kneels by her coffin and lowers his head in despair. He had no idea his kiss would wake her up.
