The story about Marty the Alien is that he is from out er space, and most people think he does not exist. Marty appears only to people who believe he is real. Marty loves to play, sing, and dance; that's why he shows up only if there are children around he can play with. Most of the time, he will show up on a child's birthday, but he is always around to teach children from his storybooks. He is known to teach children colors, spelling, and how to count. He may be from outer space, but he speaks English. Marty is a young alien boy who is still learning himself, so don't be mad if you are one of the lucky people to happen to see Marty and he doesn't know something, but he learns fast.
