Anybody recognize this cartoon capture?

Of course it's from 2004's The Legend of Frosty the Snowman, "told and sung by Burt Reynolds." The above character, pictured at the end of the cartoon, is Sara Simple, one of the kids of Evergreen, where "magic, silliness, and nonsense of all kinds are strictly against the rules." Earlier she asserts to her mom, "I don’t want to be a princess—I want to be an urban planner!" Obscure, indeed.
