The gang reunites and decides to break into a Parisian museum to scratch Sly's kleptomaniac itch, but learn that they need to travel back in time to stop the erasure of the Thievius Raccoonus through the discovery of an ancient dagger.
Tropes:
- Absurdly Spacious Sewer: Bentley's section of the level is set in the Paris sewers beneath the museum.
- Arc Villain: Cyrille Le Paradox, as it is his museum that the Gang is breaking into
- 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.
- Central Theme: All three members of the Cooper Gang make mistakes during their first thieving attempt in years; however, the gang’s trust in each other never went away, and they show support for each other despite their mistakes.
- Sly accidentally knocks over a telephone pole during his initial ascent to the top of the museum; Bentley is concerned for him, but Sly is confident that the heist will go off without a hitch.
- Bentley almost falls onto a silent alarm while trying to hack the security systems, and narrowly avoids his demise using his robotic arms at the last second. When Sly asks him how the hacking is going, Bentley feigns confidence despite being shaken by the incident.
- Murray is eventually outnumbered and overwhelmed by the rat goons, but quickly overcomes his frustration and announces he’s feeling fine to a rather confused Bentley.
- Chekhov M.I.A.: Penelope disappeared as if into thin air.
- Contrived Coincidence: The fact that Sly was planning a heist at 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.
- Furry Confusion: The enemies of the level are anthropomorphic rat Mooks, and there are also non-anthropomorphic rats seen as fauna.
- 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.
- Shout-Out: Bentley mentions in the sewers that he hasn't been there since he was a teenager.
- Time Machine: Using the tech Bentley and Penelope perfected, the Cooper Van was outfitted into this.
