'''''The Sylvester and Tweety Mysteries''''' was the second original television series of the 1990s to be [[SpinOff spun off]] from the ''WesternAnimation/LooneyTunes'' shorts (the first being ''WesternAnimation/TazMania''). It ran on Creator/KidsWB from 1995 through 2001.

The series centers on the adventures of ''WesternAnimation/LooneyTunes'' stars Sylvester, Tweety, and Hector the bulldog, and their owner Granny. Each episode, they are on vacation or called to some location where they have to solve a mystery going on, hence the series' title. Each episode starts with someone calling "the greatest detective in the world" to solve a case. Said detective is always unavailable, so they give up and settle for Granny. She takes her three pets with her wherever she goes, unaware of their endless conflict.

Actually, Granny does most of the detective work, but her pets do provide help from time to time. Of course, during all this, Sylvester is always trying to eat Tweety, but Hector, taking the role of the bird's bodyguard, is always making sure he doesn't.

Many of the supporting characters had guest appearances and cameos as the episodes went on. Cool Cat, a character in the later theatrical cartoons, appeared in just about every episode as a cameo.

While the first season featured episode-long plots based around the mysteries, the following seasons split the shows into two 10-minute segments that focused less on mysteries and most being based around WholePlotReference of older cartoons.

!!Tropes present:
* AbdicateTheThrone: Some lions wanted to depose their King because their food reserves (read: game) were running low. The King wouldn't mind abdicating except that it wasn't allowed. He had to die before a new King rose. He instead tricked Sylvester into switching places with him. (Which was posible thanks to PaperThinDisguise) [[spoiler:The food was eventually found inside the cave of a lion who planned to [[TheUsurper usurp the throne]] but decided the current King wasn't all that bad when compared to Sylvester]].
* AffectionateParody: The whole series is one to ''Series/MurderSheWrote'', with Granny as a parody of Jessica Fletcher. "A Ticket To Crime" is one to ''Film/MurderByDeath''.
* AncientArtifact: In ''Good Bird Hunting'', Sylvester finds an ancient relic that lets him grow taller and muscular to fend off Pete Puma from eating Tweety with mixed results. Granny ends up taking the artifact away.
* AllJustADream: [[spoiler: The final episode when it seems that Sylvester finally ate that darn canary.]]
* ArtisticLicenseAnimalCare: Granny is the worse pet owner of all time. Some episodes has Sylvester, Hector, Tweety or any combination of the three being pet-napped, and she barely even notices. And when she does notice, it's mostly Tweety she cares about. Never mind that fact that she never notices Sylvester being horribly injured, even by the other two.
* ArtEvolution: As the show progressed, the background art starting looking more cheaper like the 60's Warner Bros. cartoons. Also, the final five episodes of the series used digital ink and paint.
* BankruptcyBarrel: In "It's a Plaid, Plaid, Plaid, Plaid World", all the Scotsmen are shown wearing barrels because the plaid they use to make their kilts have been stolen.
* BeachEpisode: "Hawaii 33-1/3" takes place at a Hawaiian beach and even features some curvaceous women in bikinis.
* BrickJoke: Occurs in the first episode "The Cat Who Knew Too Much" when Sylvester gets a window slammed on his fingers and remarks that he'll never play the cello again. Later in the episode, he prepares to play one while pretending to be part of a band with Granny, which causes him to say to the audience "So I was wrong".
* ButtMonkey: Sylvester, but he tends to bring it upon himself.
* TheCameo: Like most WesternAnimation/LooneyTunes shows, several other classic (usually somewhat obscure) characters would appear in certain episodes at times. Sometimes they'd even be central to the plot.
** Cool Cat appears in almost every episode, though usually as background image rather than a character.
* CassandraTruth: Oftentimes Granny and her pets traveled to spooky places like a mummy's tomb or a haunted house, and Sylvester would be the only one who saw the danger they were in. Naturally no one believed him.
** This doubles as a ShoutOut to Sylvester's role as Porky Pig's pet trying to protect him from murderous mice in an old hotel in one of the old shorts.
* CatsAreMean: Sylvester, par for the course, is always intent on eating Tweety and isn't very scrupulous in general.
* ChewToy: Even when Hector isn't beating him senseless, even the universe itself likes to make sure Sylvester gets hurt as often as possible. Not that he doesn't deserve it.
* ChristmasEpisode: "It Happened One Night Before Christmas" in season 1 and "Feather Christmas" in season 4.
* CluelessMystery: Often the writers didn't [[FairPlayWhodunnit play fair]] and Granny would solve the mystery with clues that the viewers couldn't see until TheUnmasking.
* ColdOpening: A RunningGag concerned victims phoning the top detective to solve their cases, but the top detective is unavailable for whatever reason, so they relay the client to Granny instead.
* CoolOldLady: Granny, as always, is one of the coolest. Her career as a detective definitely helps.
* DetectiveAnimal: A mostly-accidental version. The bickering among Sylvester, Tweety and often Hector causes clues to appear in front of Granny, who then solves the mysteries herself.
* DetectivesFollowFootprints: The intro animation is all about this.
* EngineeredPublicConfession: Tweety engineers one in "Double Take", hovering over the bad guy's head with a microphone as he blabs his plan to Sylvester.
* EpisodeTitleCard
* ExactlyWhatItSaysOnTheTin: It's a show staring Sylvester Cat and Tweety Bird. They solve mysteries.
* ExpositoryThemeTune: The theme song sums up the basic premise of the show, that Sylvester, Tweety, and Granny travel the world solving mysteries.
* FailureIsTheOnlyOption: The last episode has [[spoiler:Sylvester actually eat Tweety, which results in a whole fallout that reached world crisis levels just because Tweety was gone. Good thing it was just a dream of Sylvester's.]]
* FriendlyNeighborhoodVampire: Count Blood Count is depicted this way in the episode "Fangs for the Memories". He's the episode's client rather than the antagonist and is shown to be very friendly towards Granny and her pets.
* IllNeverTellYouWhatImTellingYou: In "Is Paris Stinking?", Pepe Le Pew stole all the perfume of Paris and replaced it with his own smell. When caught, he said he'd not reveal it's hidden at the old chocolate factory.
* InTheBlood: One episode features a distant cousin of WesternAnimation/PepeLePew. That cousin behaves like Pepe and has a car that hops around the same way Pepe does while chasing female skunks or whatever Pepe and his cousin mistake for them. Pepe's cousin even mentioned the kinship to explain the behavior similarity.
* LaughTrack: Tweety's statements and antics are accompanied by this in the episode, "El Dia de los Pussygatos".
* LittleOldLadyInvestigates: The basic premise of the show is that Granny is a detective.
* {{Mooning}}: In "Curse of De Nile", Colonel Rimfire reads hieroglyphs that read "Look behind you", with the word "behind" represented by an image of a mouse grinning while exposing his butt.
* MushroomSamba: Sylvester ends up having a trippy dream sequence in "El Dia de los Pussygatos" after Tweety tricks him into eating a chili pepper.
* NixonMask: One episode features a villain impersonating the ghost of UsefulNotes/WilliamHowardTaft to scare the President away. After being unmasked, he says that he chose President Taft because, as the largest President in history, he'd make an impressive ghost and the costume shop was out of [[UsefulNotes/RichardNixon Nixon]] masks.
* PetTheDog: Or Canary in this case in the final episode.
* APirate400YearsTooLate: "You're Thor?" had Vikings a thousand years too late.
* PrivateEyeMonologue: Sylvester sometimes opens episodes with these kinds of narrations, since he has as much involvement in solving the cases as Granny, Tweety, and Hector.
* ShoutOut: To Franchise/{{Batman}} in "Outback Down Under". Sylvester at one point remarks "Get Commissioner Gordon on the phone, I think we've found the Batcave!"
* SpiritualSuccessor: The DirectToVideo movie ''Tweety's High-Flying Adventure''.
* TitleDrop: Sylvester says the episode's title at the end of "Keep Your Pantheon".
* UnfortunateNames: Moo Goo Gai Pan, who was born in a Chinese restaurant and accidentally given the name of the daily special.
* UnusuallyUninterestingSight: Most of the crimes are committed via classic WesternAnimation/LooneyTunes slapstick or in some otherwise bizarre and outlandish manner. Some of them are still perceived as accidents at first, even when they happen right in front of Granny herself.
* VertigoEffect: Parodied in one episode.
* WithFriendsLikeThese: Sylvester, Tweety, Hector and Granny are a team of crime-solving supersleuths (though Granny does most of the work). This does little to stop Sylvester from trying to eat Tweety all the time, or Hector from beating on Sylvester constantly whether or not he's actually tried to eat Tweety recently.
* XMeetsY: It's ''WesternAnimation/LooneyTunes'' meets ''Series/MurderSheWrote''.
