Ratbo the Exterminator

 is a Boss enemy.

Background
Many tales are told of Ratbo and most Scrat agree they can't all possibly be true. One of the stories say he was a stowaway on another clans barge. At first he simply tied to live in the bowels of the ship in especially by the local enforcer on the airship and never left alone. However no matter how many Scrat were sent to hunt him he would kill them all time and time again

Another story tells of how he by himself went deep into an enemy held land and rescued his beloved machine gun that had been stolen. Along the way he accidentally freed many prisoners whom now form the majority of his clan.
