Last known sightings claimed she headed out of civilization and deep into the Haitian jungle.
― Sly Cooper[src]
On the way to their next destination, Sly Cooper studied up on Mz. Ruby. She was born into a family of voodoo mystics and was often feared as a child. She, therefore, had to resort to making friends with the undead. As an adult, she used her powers to punish the world for fearing her as a child. Upon joining the Fiendish Five, she eventually fled into obscurity, hiding deep within the Haitian jungle.
|"The Dread Swamp Path"|
|Sly and the gang arrived at Mz. Ruby's swamp. Sly made use of his new Rail Walk move on the vines of the swamp to explore the dreadful place.|
|"The Swamp's Dark Center"|
|Sly found Mz. Ruby's main base of operations. Sly had to first find a way to the other side of the facility and then figure out how to get up to Mz. Ruby's skull temple.|
|"The Lair of the Beast"|
|Sly ventured through a swamp-filled area that was home to a giant serpent known as the Beast.|
|"A Grave Undertaking"|
|Sly entered a haunted area filled with ghost rats. He was to fight his way through the ghosts and find another key before he would become one of them.|
|To collect a key here, Sly had to make use of a swamp skiff and use its flamethrower to light 25 tiki torches, which in turn would unlock the gate to the key.|
|"Descent Into Danger"|
|Sly explored the center of Mz. Ruby's operation, a waterfall overflowing with bones and body parts, which Mz. Ruby would use to create her ghosts.|
|"A Ghastly Voyage"|
|Sly had to use a hover blaster to destroy many of the gravestones spawning ghost rats. He had to be careful here, though, as the ghosts were not going to make things easy, and one bad move could earn him a one-way trip to the depths of the swamp.|
|"Down Home Cooking"|
|Bentley made a deal with one of Mz. Ruby's ghosts, who promised to give Sly a treasure key if he could whack 50 chickens for the ghost's pot of gumbo. Sly had to do so within a limited amount of time, while also avoiding the bomb toting roosters.|
|"A Deadly Dance"|
|Sly fired his way up to the Skull Temple to face off against Mz. Ruby in a Simon Says-styled showdown.|
Mz. Ruby's section of the Thievius Raccoonus contained an entry for Sly's pioneering ancestor Slytunkhamen Cooper, whose Invisibility technique allowed him to steal from corrupt pharaohs and greedy noblemen. Carmelita showed up and once again failed to capture Sly but instead slapped the cuffs on Mz. Ruby. Her production of zombies, which were made illegal in the World Peace Accord of '71, earned her a life sentence behind bars.
Sly and the gang enjoyed a few weeks in the tropical sunshine, working on their tans in preparation for their next caper.
