The Blockheads are using insecticides on their farm, much to the dismay of the local earthworms. Fortunately, Gumby is the self-appointed guardian of all earthworms, and he rigs up a net to crash the Blockheads' crop dusting plane. Rather than press charges, the Blockheads agree to stop spraying, but then they start selling their worms as live fish bait. Gumby unites the worms of the world, and they devour the ground beneath the Blockheads' ugly, ugly house, destroying it. The worms of the world are free of their oppressors, thanks to Gumby.
