Here they are....
Vanellope Von Schweetz
Wreck It Ralph
Kids were not frightened by either character.
Ralph is similar to Sully in size, but even more limited in movement. His hands don't move, he cannot neal down, he cannot turn his head. He can only pose his arms in different positions. He might as well be a statue.
Vanellope's head (eyes) looked odd. And, she is too tall (About 5'10" - 6' and 6'4" to the top of her hair). However, she was very good with pantomime. She would dance around, pretend to be racing a car, had many poses, and can move her head and hands. She had spare time waiting for people to finish with Ralph and was fun to watch pose, dance, lean against the side, wave to the crowd, mimic the movements of the kids, etc. She had personality, Ralph was a big dud.
But, I really wish she were a "face" character you could talk to.
