The show focuses on the titular Baby Shark (Kimiko Glenn), a young shark who lives in the underwater town of Carnivore Cove with his parents, Mommy Shark (Natasha Rothwell) and Daddy Shark (Eric Edelstein), and his grandparents Grandma Shark (Debra Wilson) and Grandpa Shark (Patrick Warburton). Along with his best friend William (Luke Youngblood), Baby Shark has a variety of adventures, while making new friends and singing songs along the way.
The first episode, the Christmas special "All I Want For Fishmas", debuted in December 2020, with the show proper debuting in March 2021. In anticipation for the release, "Baby Shark's Big Show Shorts", a collection of two-minute shorts, were released in February 2021.
The show includes examples of:
- Amazing Technicolor Wildlife:
- All of the Shark family are in a variety of bright colors that real sharks don't come in: Baby Shark is yellow, Mommy Shark is pink, Daddy Shark is blue, Grandma Shark is orange, and Grandpa Shark is green.
- William is a pilot fish, but is bright orange, instead of the standard black-and-white stripes of the real species.
- An Aesop: Almost every episode contains one:
- "All I Want For Fishmas" is about how Christmas is about giving, not receiving.
- "Baby Tooth" is about patience.
- "Slobber Slug" is about how talking out problems with others is sometimes the best thing to do.
- Animated Adaptation: Of a sort. The show is adapted from already animated music videos, with a new style compared to those.
- Art Shift: The theme song starts in the traditional lineless Pinkfong art style, before shifting to the show design.
- Canon Foreigner: The Shark Family and William are the only characters that existed prior to the show, with all the other characters being created specifically for it.
- Christmas Episode: The episode "All I Want For Fishmas" takes place during "Fishmas", the undersea equivalent of Christmas. All of the children in Carnivore Cove want the Burpin Bubz, the hottest toy of season. Unfortunately, this puts a toll on Santa Jaws, nearly shutting down Fishmas for good.
- Cyclops: Ernie Urchin only has one eye.
- DIY Dentistry: The episode "Baby Tooth" has Baby Shark's tooth go loose, causing him to be desperate to pull it out when it's not ready. After attempts from William tackling it fail, the two of them tie it to an anchor and throw it in the Water Ways where it does pull out, but also is dragged through with the anchor.
- Excited Show Title!: Baby Shark's Big Show!
- Flintstone Theming: The show has everything modified for an undersea community. Water spout currents are used instead of roadways and falling snow is instead small jellyfish.
- Full-Name Ultimatum: Mommy Shark refers to Baby Shark by his full name of Baby Shark Brooklyn when he chews on the kitchen table in impatient hunger in "Baby Tooth".
- The Gadfly: Grandma Shark. In "All I Want For Fishmas", she wraps a sleeping Grandpa Shark up in wrapping paper, and she places a whoopie cushion on his chair in "Baby Tooth". She insists that "pranking is a virtue", as it teaches spontaneity.
- Gasshole: The "Burpin' Bubz" toys in "All I Want For Fishmas" are bubble-shaped objects that belch when they're squeezed.
- Happily Adopted: Hinted to be the case with William. His mom is a manta ray, while he is a pilot fish.
- Hold Your Hippogriffs: Various words are replaced with fish-based equivalents. This is lampshaded in "All I Want For Fishmas", during the "Coraling Melody"Coraling is caroling,
Except we're in the sea!
- Informed Species: William is meant to be a pilot fish, but has an orange color scheme that more resembles a goldfish.
- Multigenerational Household: Baby Shark lives with both his parents and his grandparents.
- Mythology Gag: Baby Shark's full name is "Baby Shark Brooklyn", in reference to his name given to him for his exclusive YouTube channel.
- New-Age Retro Hippie: Grandma Shark is portrayed as a peaceful woman in-tune with nature. Despite this, she has a surprising prankster streak as well.
- Non-Mammalian Hair: Grandpa Shark has bushy eyebrows and a moustache.
- Seahorse Steed: While citizens that are seahorses exist in Carnivore Cove, such as Chucks, animal-like ones exist as well. Santa Jaws has his sled pulled by reindeer-like seahorses.
- Seldom-Seen Species:
- William is a pilot fish (despite having an entirely different color scheme), a kind of fish often seen around sharks as an aiding fish.
- "All I Want For Fishmas" features a sea angel, a kind of sea slug, subbing for a literal angel.
- Baby Shark replicates Kevin's scream from Home Alone in "All I Want For Fishmas" when he learns that Santa Jaws has gone missing.
- "Baby Tooth" has the Tooth Fish Fairy asking "Why did it have to be sea snakes?".
- The episode "Slobber Slug" takes a lot from The Sandlot in terms of plot, featuring a baseball-esque game hampered by a large dog-like creature.
- Subbing for Santa: Downplayed, in "All I Want For Fishmas", Baby Shark and William are helping Santa Jaws, rather than fully subbing for him.
- Surprisingly Realistic Outcome: The seabird in "All I Want For Fishmas" is unable to give information on the missing Santa Jaws, as not being able to breathe underwater means he's unable to waste his time talking.
- Theme Tune Cameo: In "All I Want For Fishmas", William wakes up Baby Shark by singing the first part of the classic song.William: Baby Shark...
Baby Shark: (snaps awake) Doo-doo-doo-doo-doo-doo!
- Threatening Shark: Inverted, Baby Shark and his family are a kind and cheerful bunch.
- True Meaning of Christmas: The episode "All I Want For Fishmas" has Baby Shark and William and later Santa Jaws himself learn that it's better to give than to receive during the holidays.
- You Mean "Xmas": Under the sea it's "Fishmas". Instead of Santa Claus, Santa Jaws is the one to deliver presents, with a sleigh pulled by reindeer-seahorses.
