The first season centred on the "Search for the Grand Baby" plot. An alien race of children exist on the moon, known as Moonlings. Their leader, The Grand Baby, is fast approaching the end of his life, and without an heir, it is decided that a great power will be sent to Earth to choose a new leader for the people there. The power itself, consisting of all the psychic and magical abilities that the Grand Baby possessed, arrived on Earth but hit the Mellops' crystal punchbowl, "splitting" around the house, hitting several household items.
