In Small is Beautiful, during the Super Planet Competition Dark Truder shrinks all nine* planets. When Multo tries to come to the rescue he is accidentally shrunk as well. Truder places the shrunken planets, and miniature Multo, into a sack and rockets away, threatening not to return them until he is proclaimed Ruler of the Universe. The Zula Patrol races after Dark Truder, but before they can come to the rescue, Multo gets the planets to work together to break out of the sack. Once out of the sack, Multo is able to return the planets and himself to normal size. Everyone learns that being small doesn't mean you can't do big things.

*After this episode was created Pluto was reclassified as a dwarf planet. There are currently 8 planets officially recognized by the International Astronomical Union (IAU).
