Baby Looney Tunes

Baby Looney Tunes is an animated program that ran from 2002 to 2005. Similar to Muppet Babies, this program features baby versions of Bugs Bunny, Daffy Duck, Lola Bunny, Taz, Sylvester Cat and Tweety Bird and other Looney Tunes characters with Granny as their caretaker. Her grandson, Floyd, was introduced in the third and final season, and other Looney Tunes members either make cameo appearances in songs, or they appear as a guest in some episodes.

Tropes used in Baby Looney Tunes include:

An Aesop
Annoying Laugh: An episode had the gang laughing at Sylvester's failures.
Big Eater: Taz.
Blonde, Brunette, Redhead: Lola Bunny, Petunia Pig and Melissa Duck in that order.
Bring My Brown Diaper: This line from Sylvester:

Sylvester: "Good thing I brought a spare diaper!"

Broken Aesop: In one episode where they went apple picking, Melissa insisted to the others that her picking method was better than the others', at which point they decided to have a race to prove which was the best. It ended in a tie, giving the Aesop that everyone's methods of doing things should be respected. However, the farmer taught her that method, making the Aesop come off as "it's okay to ignore the advice of the local authority figure".
Butt Monkey: Mostly Sylvester.
Call Forward: In the episode Duck Reflucks, there is a sequence in one point that is vaguely similar to Duck Amuck, but with the roles reversed, with Daffy being the tormentor with Bugs being the tormented.
Canon Foreigner: Melissa Duck. This is not the same Melissa that appeared in The Scarlet Pumpernickel cartoon.
- Also Floyd.
Cats Hate Water: Sylvester.
Children Are Innocent
Cool Old Lady: Granny.
Curtains Match the Window: Petunia.
Cute Kitten: Sylvester has some kittenish habits, such as playing with yarn.
Cute Little Fangs: Taz.
Dark Horse Victory: Twice by Sylvester, in Cat-Taz-Trophy and The Puddle Olympics.
Death Glare: In "Pouting Match" Lola starts pouting whenever she doesn't get her way. When the other babies start using the same trick she ups her game by switching to Crocodile Tears.
Duck Season! Rabbit Season!: Played with in "School Daze", where Daffy and Bugs arguing over who gets to sit in front of the bus while pretending to play school. Bugs wins, of course. The original short is even referenced.
Edutainment Show: Given the morals, it's not suprising...
Hair Decorations: Lola, Melissa and Petunia wear hairbows.
Fiery Redhead: Melissa.
Friendly Tickle Torture: Lola and Bugs shares one in an episode.
Fun with Flushing: The main characters wonder about the toilet in the bathroom and form their own theories about how dangerous it is, while Petunia assures them nothing is wrong. In the process, they panic when Petunia accidentally flushes it, and puts toilet paper to "Feed the monster," clogging it up. They accidentally leave her in and she comes out wet with toilet paper on her. When Granny shows her what the toilet is really for, and Petunia tells them, they don't believe her.
Girlish Pigtails: Petunia.
Green-Eyed Monster: Sylvester towards Pepe in "New Cat In Town".
Gosh Dang It to Heck: An episode involves Daffy swearing.
I Got a Rock: Keeps happening to Daffy when the babies go trick-or-treating, even when he's trick-or-treating the same houses as the others.
Insult Comic: Melissa becomes one after seeing one on TV. It doesn't go well, needless to say.
Jaded Washout: Despite being a toddler, Sylvester has some shades of this.
Lighter and Softer: BLT is quite a radical departure from the wanton violence and other antics of the classic Looney Tunes.
Lovable Coward: Sylvester.
Mouthy Kid: Melissa.
Mr. Fixit: Marvin.
Never Say "Die": Granny says her mother "lives a long way away from now" in one episode.
Nightmare Fuel: In-universe. In one episode, Granny tells the kids the story of the Sandman to explain the sleep in their eyes, unintentionally terrifying Daffy, who decides to Never Sleep Again. (And when he does manage to stay up all night and his friends have sand in their eyes anyway, he's even more frightened because he has no idea how the Sandman got past him.)
Nobody Poops: Partial aversion; School Daze mentions they're almost potty trained, and in Flush Hour, Petunia tells them what the toilet is for after using it off screen:

Petunia: "It's diapers plus!"

The Napoleon: Tweety usually isn't bad tempered, though some episodes deal with disadvantages he has because of his small size.
Neat Freak: Sylvester.
Non Indicative Title: Initially, they were a lot like actual babies with the obligatory "What the hell is that white, water-filled chair in the bathroom?" plot, but as the show ran, the only thing that kept them from being full-on kids is that they were under school age. In fact, the later episodes don't have them in diapers, unless it's in one of the intermission songs.
Non-Mammalian Hair: Melissa.
The Quiet One: Marvin.
Ridiculously Cute Critter: All the characters could count, but Baby Pepe takes it all the way Up to Eleven in the episode he appears in.
Shrinking Violet: Marvin.
Show Within a Show: Types 1 and 3 are used in "Eye Strain", where Petunia watches her friends reenact her favorite shows, such as Care Away Street, Beanbag the Dinosaur and Mint's Hints as well as other shows.
Slice of Life
Theme Tune Roll Call
The Smurfette Principle: At first, it was just Lola. Later episodes added Melissa Duck and Petunia Pig to the cast.
Spinoff Babies
Small Name, Big Ego: Not surprisingly, Daffy.
Tertiary Sexual Characteristics: The girl characters have hairbows.
The Three Faces of Eve: Melissa (mother), Petunia (child), and Lola (seductress).
The Unintelligible: Taz. Tweety often translates for him.
