The Blockheads sell their forest land to developers who are itching to make a freeway, and it just puts Gumby in a bad mood, what with how the freeway will ruin his farm's ecology. Meanwhile, Pokey is eating a carrot, inspiring a local beetle to instantly grow to fifty times its normal size for five seconds. Disregarding the dangers involved with giant insects, Gumby decides to use the bug's strange properties to scare off the driver of the Caterpillar tractor that's clearing the forest. When another driver comes by, Gumby uses his own size-altering powers to scare him away, leaving us to wonder why he needed the stupid bug in the first place.
