When designing this character I tried to make her body realistic and kid friendly, keeping in mind the origin of her game. I really liked the first movie, not sure how I feel about the second one or where it took the characters. That one meme is pretty good though, I think it still has a lot of potential.
Looking into other parts of the fandom, one of the most popular concepts for Vanellope is aging her up, taking the Sugar Rush characters in a more adult direction, often with a more classic anime style. It looks like fun, but I'm not too interested in the other characters, just not as much to them.
