Trouble is brewing beneath Serene Greens! Hapo the earthworm needs help underground, but how can the CyberSquad possibly help their miniscule friend? With one zap of Digit's "shrinkray," the team shrinks to the size of tiny insects and portals underground. They're literally IN the soil! The diminutive Matt, Jackie, Inez, and Digit come face-to-face with all sorts of critters that make up this thriving ecosystem. The only problem is Hapo's home turf, Bug Bayou, is anything but flourishing. The roots are mushy, the ground is clumpy and dry, and food is scarce, causing creatures to flee to healthier ground. Something is damaging Hapo's soil. But what? The CyberSquad digs in to get to the root of the problem.
