The Newsboy (AKA. Leonard) is a character in Walking on Wall Street. He is a chubby boy with spiky red hair, a turned-up nose, and an orange sweatshirt, but he is dissimilar to a Supernoobs character. His best animal friend is Lester the Investor. His appearance is similar to a monkey's (possibly Curious George), with big ears and a turned-up nose.
It's unknown which child actor voiced him. Same goes with Leroy (the broker).
