| The Iron
        Chicken called the Sky-moos to the Clangers' aid when
        their planet became covered with green plants. Since then
        the Sky-moos have often called on the Clangers. They just
        come to say hallo and pass the time of year, but they
        secretly hope the Clangers will one day grow another huge
        field of green plants for them to eat, because Sky-moos
        are great eaters of greenery and there is a shortage of
        green vegetables in space. N.B. using ears as wings is only possible in low gravity conditions (not recommended on earth) |
