Rotter gives the foxes failed passages to the barnyard via a Trojan Chicken, whilst tipping the Foxbusters in return for some eggs. When both sides see they've been duped, they deliver payback to Rotter.

The foxes have been kidnapping rabbits and forcing them to dig a tunnel to the farmyard. The Foxbusters get trapped entering the tunnels until Moleier rescues them and they all thwart the foxes' scheme.

A long democratic campaign battle ends up with Dog winning leadership of the Foxbusters, which backfires when the foxes come for their gain. The Foxbusters regain their positions and fight off the fox invasion.
