The gang decides to break into a museum, which serves two purposes; scratches Sly's kleptomaniac itch, and allows them to travel back in time to stop the erasing of the Thievius Raccoonus.
- Absurdly Spacious Sewer: Bentley's section of the level is set in the Paris sewers beneath the museum.
- Call-Back: Bentley brings the same jar of cookies that the Cooper Gang stole as children for their first heist to share when he and Sly hook back up.
- Chekhov M.I.A.: Penelope disappeared as if into thin air.
- Contrived Coincidence: The fact that Sly was planning a heist for the Paris Museum originally had nothing to do with the artifact Bentley needed for his time-machine. Sly just wanted to do a heist to satisfy his thieving instincts.
- Early-Bird Cameo: While sneaking past the windows in the museum, you can catch a glimpse of Le Paradox, Toothpick and Decibel's silhouettes discussing their Evil Plan.
- Gay Paree: Much like the first game, the first level of this game takes place in Paris.
- MacGuffin: The museum heist was all for a 17th-century Japanese dagger to use on the time machine.
- Putting the Band Back Together: When Sly plans his heist, Bentley and Murray rejoin with him as though nothing ever happened. Murray even drops everything in his now lucrative monster-truck career just to be a thief again.
- Ripple Effect Indicator: Bentley realizes that his time-travel tech has been plagiarized when he sees that the Thievius Raccoonus starts vanishing one page at a time.
- Time Machine: Using the tech Bentley and Penelope perfected, the Cooper Van was outfitted into this.
