3. Happy Feet (2007)
More penguins! Because everybody loves 'em. Writer-director George Miller, who entranced families in the '90s with "Babe," moves from the farm to the Antarctic in this inspiring and thrilling cartoon. Little Mumble is the oddball penguin who can't sing like everyone else, but he sure can dance (his motion-captured routines were performed by Savion Glover). A surprising but deserving winner of the Best Animated Feature Oscar, the movie's full of vibrant messages about respecting those who aren't like you-and respecting the planet, too.
