|Location||Great Forest (currently)|
The K-9 Patrol is a group of Mobians, mostly canines (except for Beverly Beaver) which is where the name came from, who share the same goal as the Knothole Freedom Fighters; to stop Robotnik.
Residence in the Great Forest
While traveling from the Kingdom of Nobletail, the K-9 Patrol eventually came upon the Great Forest. Deciding that a proper base could be built here, they excavated an underground hollow (very much like the Knothole HQ) and named it K-9 HQ.
Alliance with the Knothole Freedom Fighters
Eventually, the K-9 Patrol decided to make their base larger, so they dug out more space, moving in the direction of Knothole Village. At the same time, the Knothole Freedom Fighters were also enlarging their base. Eventually, the two groups ran into each other. A short argument ensued, with the K-9 Patrol accused of being "spies". When Sally asked Wolfen Von Nobletail why he and his friends were down here, he said that they had building a base to live in where they could plot against Dr. Robotnik. Realizing that the K-9 Patrol were good guys and that they had the same goals as the Knothole Freedom Fighters, Sally introduced herself and her friends, while Wolfen and his friends followed suit. From that day, the Knothole Freedom Fighters and the K-9 Patrol had become allies.
