----
!!This episode contains examples of:
* AbusiveParents: Peter punches Chris (giving him a black eye) just to stop him from getting the treasure first. Lois is appalled that Peter ''hit his own son'' for such a stupid reason and gives up on the treasure hunt on the spot. Even after his HeelRealization, he thinks Chris has already forgiven him.
--> '''Chris''': ''[holding an ice pack on his black eye]'' I can't wait until you fall asleep tonight.
* AllJewsAreCheapskates: Mort Goldman is shown telling his son to connect to their neighbor’s Wi-Fi.
* ArtisticLicenceHistory: In-universe. Lois questions why everyone was convinced that the last clue led to a baseball stadium, because baseball wasn't invented until the 1800s. This leads her to figuring out the Drunken Clam as the real location.
* AskAStupidQuestion: Lois wonders what's in an ice cream cone after listing all of the ingredients. ''Peter'', of all people, has to point this out.
--> '''Peter''': ''[annoyed]'' You just listed off all the ingredients! ''Everything you just said'' is what's in that!
* BlatantLies: Meg mentions that she was in a play about Miles “Chatterbox” Musket that no one in the family went to, sarcastically thanking everyone for going. Stewie and Brian make excuses but Peter says “weekends I like to spend with my kids.” He’s saying this to his daughter.
* BodyHorror: A fairly minor one played for laughs when Meg is clinging to Chris on a jet ski.
-->'''Chris''': Your nipples keep poking me.
-->'''Meg''': Sorry. That happens when I get cold.
-->'''Chris''': But why are there three of them?
-->'''Meg''': There aren't. Two of them are moles.
-->'''Chris''': Those numbers still don't add up!
* ChekhovsGag:
** The cutaway depicting a commercial for a "Hurry Up Shrimp" food delivery service would be forgotten until the very end, when the Griffins get a knock on their door and Peter assumes it's the delivery guy.
** Also, Meg makes mention of her family walking out of the play she was in about the founding of Quahog. Later, Lois solves the location of the treasure by citing some history she heard during her ten minutes at the play.
* DidntThinkThisThrough: When Stewie tries to fart at Peter in retaliation for Peter's bad breath, it backfires due to the fact that there's a fan in the same room as him and Peter.
* HalfwayPlotSwitch: The first part of the episode is about Peter's bad breath and how it affects his family. After Lois forces him to go to the dentist and he gets it sorted out, the family celebrate by going to a restaurant. There, Peter learns of a mysterious treasure, and the rest of the episode is about everyone's quest to find it.
* HeelRealization: Peter when he sees what the obsessive search for the treasure has done to everyone.
* JawDrop: Peter's reaction to hearing the story of the treasure.
* JerkassBall: Bruce is one of the citizens joining the treasure hunt, and is seen fighting at the stadium later on.
* JerkassHasAPoint: Peter rightfully calls out Joe and Quagmire after they wanted to join the treasure hunt, despite them not believing Peter earlier and even mocking Peter for believing that there was treasure in the first place.
* LeaningOnTheFourthWall: Peter and Lois get inside the closed Drunken Clam by setting up a CutawayGag to transport them inside.
* ScrewThisImOuttaHere: After Peter punches Chris to stop him from finding the treasure first, Lois calls it quits on the treasure hunt.
* ShaggyDogStory: The "treasure" turned out to be a coupon from the Founding Father restaurant... which already expired.
* SnarkBall: Peter in the cutaway where he complains about how Lois orders ice cream:
--> '''Lois''': ''[looking at the menu]'' Ooh, "coffee fudge swirl with Reese's Peanut Butter Cups"... Oh, I wonder what's in that.
--> '''Peter''': ''[annoyed by Lois' behavior]'' You just listed off all the ingredients! ''Everything you just said'' is what's in that!
* UnwittingInstigatorOfDoom: The waiter at the Founding Father's restaurant told Peter about the treasure map, sparking his desire to find it and eventually leading to him attacking ''his own son'', graverobbing, and a mass brawl between the Quahog residents for what turned out to be a coupon...that expired seven years ago.
* VomitIndiscretionShot: A cutaway depicts Peter's bad breath making an employee vomit nonstop.
* WhatTheHellHero: Lois says this to Peter this when he punches Chris to get the treasure, causing the family to leave the hunt.
* WholePlotReference: The setup is a parody of ''Film/ItsAMadMadMadMadWorld''.
* WouldHurtAChild: Peter was just about to kill a kid with a shovel (who was also looking for the alleged treasure) before the show quickly cuts to the next scene. He also punches Chris just so he can get to the treasure first.
