The translation of the scroll to restore the spell protecting San Lorenzo is finally complete and the last treasure is ready to be returned... except the Silver Sphere isn't quite the last treasure. After a meticulous search of the treasury inventory, Puss realizes the one treasure that is still missing is the future gold coin Puss removed from the treasury in the first place, which has fallen into the hands of the Duchess who plans to use it to power a magic suit of armor to finally get her revenge on Puss and San Lorenzo.
- Ambiguous Time Period: It's never said what year it actually is, but what makes the gold coin from the first episode special is that its dated 1829, which is said to be hundreds of years in the future.
- Compound Title: Simply meaning "Yes" in Spanish, it pairs up with the following episode "No?" as Yes and No, but also combines with the following episode to make "Sino?" which foreshadows Mage Sino's appearance a the end of this episode.
- Despair Event Horizon: Puss comes close to this when faced with the Duchess' magic armor, which is so powerful his only plan is to return to San Lorenzo and try and restore the barrier before she can catch up. He loses it when it's revealed the additional preparations to cast the spell will still take another few days.Puss: I know! I'll dig a protective moat around San Lorenzo using the power of punching! (Proceeds to rapidly punch the ground to no effect until he wears himself out)
- Artephius finishes translating the spell and shows concern that the ingredients involved are more typically used for evil rituals than they are barriers, but Uli tells him to ignore it and continue working. He also reveals some knowledge of Alchemy which he passes it off as his species having a basic knowledge of it.
- When Great Mage Sino appears, Artephius shows immediate doubt.
- It's All About Me: Puss seems less concerned about the safety that restoring the barrier will bring to San Lorenzo than he is about the idea of the idea that the town will be so grateful that they will likely build a statue in his honor.
- Jerk Ass Has A Point: Mage Sino calls out that all Puss' heroics are nothing more than him making up for a mistake he himself caused. Puss fully agrees with him on this which is why he doesn't even put up a fight when Sino banishes him from the town.
- Mundane Made Awesome: Puss makes Super-Speed Reading out to be a Dangerous Forbidden Technique that blows him away after using it.
- Near-Villain Victory: The Duchess has victory in her grasp, up until the sudden appearance of Sino.
- New Powers as the Plot Demands: In order to track down exactly what item is still missing from the treasury, Puss uses his previously unmentioned ability of Speed Reading to go through the entire checklist in a few seconds.
- No Ontological Inertia: Averted, the magic coin was only needed to activate The Duchess' magic armor. Removing it does nothing to stop her.
- Object Tracking Shot: "I wonder what happened to that coin..." cue "What Happpened to that Coin", a short montage showing the hands the coin has passed between since the first episode.
- Super-Speed Reading: As a Dangerous Forbidden Technique, even!
- Wham Episode: Great Mage Sino abruptly appears in town, and banishes Puss in Boots for his part in breaking the spell.
- Where It All Began: The last piece of treasure that needs to be returned to the treasury is the first piece of treasure that was removed from it.
