A purple alien and three kids, Kristine, Kevin and Brian try to save the environment. They are often helped by Megabrain who is only a floating head with hands

    The theme lyrics:(listen/read carefully as many people dont interperate this correctly)

    "Danger and evil are everywhere,
    Nature called he didn't care,
    Who can help the world survive,
    Who can keep a dream alive?
    alive alive!"

    "An Awesome alien hero,
    was destine to hear the cry,
    A watcher known as widget,
    he shot down from the sky!"
    "woh-oh woh-oh,
    Widget the world watcher
    woh-oh woh-oh,
    Widget the world watcher"
