- Infiltrate the prison.
- Rescue Slytunkhamen Cooper.
How to Complete & Dialogue
As Sly, reach the marker near an oasis. This piece of dialogue will begin once you do.
- Bentley: Sly, I don't know how to tell you this, but... well... you're going to have to go back to that prison again.
- Sly: WHAT?! No way Bentley! I'm not going back in there!
- Bentley: It turns out that whoever that pharaoh was locked up Slytunkhamen Cooper in there. We don't have a choice.
- Sly: Okay, okay, okay. We're going. But I gotta tell you, Bentley. That place was brutal.
- Bentley: It definitely looks like it. But just be careful, okay?
- Sly: Yeah, I gotcha. (groans) This is going to be a really long day.
Gameplay resumes as Sly Cooper heads down a dirt road leading to the prison gates. Once Sly gets close enough to them, he'll be in a new area. Sly has to crawl under a small hole to the left of the gates which leads to area full of laser security and Dangerous Donkeys. This piece of dialogue plays out when this happens.
- Sly: Uh-oh. Looks like they really beefed up the security since last night. Bentley, do you think there's a way around this?
- Bentley: Well, those donkeys look like they haven't slept in days. When they doze off, try making a dash for the small tower they're guarding. Just don't get hit by the lasers.
Quickly dodge the lasers and the guards' torchlights and Sly will head toward a small tower behind the last guard, who is fast asleep. Climb up the tower to reach a rope that Sly can Rail-Walk on. The rope will lead to another tower, this one being much more heavily guarded. Repeat the same strategy as before and Sly will reach the main cell blocks. Inside the last of these is a Secret Sly Mask. To Sly's right of the cell block is solitary confinement. To get inside, Sly needs to use the Ninja Spire Jump on some spikes blocking the path to the cell's door. Once the door has been reached, this bit of dialogue starts.
- Sly: This must be Slytunkhamen's cell. It has to be if it was this well protected.
- Bentley: Is there a way in?
- Sly: No, but I see a terminal near the cell door. Hmm... You thinking what I'm thinking?
- Bentley: You bet I do, Sly. Come to me, my pretty!
Sly will place a portable hacking device on the terminal, allowing Bentley to hack it via the mini-game System Cracker. Once that is accomplished, the cell door will open and this cutscene will commence.
- Sly: (Sly slowly approaches Slytunkhamen) Slytunkhamen?
- Slytunkhamen: ...
- Sly: Listen. I'm here to save you. I'm your descendant from the future. The name is Sly. Sly Cooper.
- Slytunkhamen: ...
- Sly: You do see my cane, right? (Sly thinks for a little bit, but then figures out what he needs to say) Look, my gang and I need you to help us take down that pharaoh who locked the two of us up. You in?
- Slytunkhamen: ... Now you're speaking my language. Let's go! (Sly leads Slytunkhamen back where Sly had come)
- Sly: "Slytunkhamen wasn't too trusting of us at first, but when I showed him the Thevius Raccoonus, he immediately believed us. Much to our delight, we were finally told who that pharaoh was. But it was the details that made this revelation so shocking. Slytunkhamen informed us that the pharaoh was a mysterious foreigner named "Qwerty". After some data-crunching, Bentley managed to uncover his Interpol file. An Austrian university professor living in Holland, Qwerty found himself out of work, and began watching the ACES Tournament for inspiration. When we defeated the Black Baron, a.k.a. Penelope, Qwerty got the idea to research us. Over time, he began to study each member of the gang and practice the use of our moves, especially mine. It would seem that Qwerty thought my disappearance meant I was dead, because he began calling himself "The Best Thief on Earth", using his skills in advanced scientific and mathematical formulas to pool off amazing heists around the world. Needless to say, he probably wasn't very happy to learn that I was still alive. I'm not sure what Penelope and Qwerty are trying to do, but something tells me that there's more going on here than we realize. We need to be careful here. Qwerty seems smarter than he looks."
- The mission's name, "The Boy King of Thieves" is a play on one of Tutankhamen's titles, "The Boy King".
