Cogs have different levels of difficulty to defeat. When a Toon's attack is strong enough, the Cog will explode and the Toon does a victory dance. If a Cog manages to defeat a Toon, the Toon goes sad and the Cogs do a victory dance.
The Cogs were created accidentally by Scrooge McDuck when he matched blue and red wires inside a robot Gyro Gearloose was working on. The robot grew evil and started to create smaller robots called Cogs. It is rumored that the evil robot is the Chairman, the leader of all Cogs.
