Bentley: ...I'm going to need some raw materials. The trick is going to be finding some quality wood, leather and metal.
Sly Cooper: Sure. Anything else you want me to pick up while I'm out? Eggs, milk... maybe some wax for your shell?
― From the mission briefing[src]
Sly needed to gather some specific materials so that Bentley could produce a new costume for him.
Bentley pointed out that Sly would need a more appropriate outfit in order to infiltrate the circus and free Galleth. Sly needed to gather some raw materials from around town, particularly some wood, leather and metal. Sly ventured out into town for clues on where to find these items.
He came across two guards and eavesdropped on their conversation, which revealed the location of a metal alloy: the local tavern. After stealing the metal and leaving the building,[note 1] Sly eavesdropped on two more guards, who revealed that the bakery was where one would find wood. As soon as Sly found the building, Bentley needed to hack the terminal to let him inside. Once Sly stole the wood from the flaming furnaces, he went out to find more guards to eavesdrop on. This time, he learned that he would find leather at the shoemaker's. Once Sly entered the building, he found the place was secured with green lasers, prompting him to believe something fishy was going on. For now, Sly made his way across the room and stole the leather. With all three items in Sly's possession, Bentley was sure he would be able to make some very useful items for him.
- When Sly exits the tavern through the front door, he reappears on the roof. This is likely an oversight by the developers.
