Fifty! Eat that you incarcerating suckas!
― Murray, after defeating the fifty inmates.[src]
Sly needed to get Murray thrown into solitary confinement in order to make his rescue less difficult.
Bentley was able to find a weakness in the solitary confinement cell and needed Sly to relate the plan to Murray. Sly found his way to Murray's cell block by crawling through a water pipe. He silently called out for Murray from the hole in the back wall. Upon seeing Sly, Murray was glad to see him, mentioning that he was feeling a little strange after being forced to eat meals covered in spice. Sly discussed Bentley's plan with Murray, explaining that if he could get in a big enough fight, the guards would throw him into solitary confinement. Murray was up for the task, believing he could take down a total of fifty foes.
Murray began fighting the wolf guards wave after wave until the counters reached 50. Once the fight was over, the plan followed through, and the guards threw him into solitary confinement.
