Charlie volunteers at the children's hospital. He thinks it would cheer the patients up if there were a colorful mural painted on the wall of the children's wing. Since Charlie can barely draw a stick
figure, he posts on social media asking if any of his artistic friends would be willing to lend their
time and talent to help make this mural a reality.
