You think you know Hello Kitty. You’ve seen the bow, the lack of a mouth, and the global takeover of everything from toasters to jet planes. But if you're trying to navigate the actual lore of her universe, you're going to hit a wall pretty fast without a solid Hello Kitty critter guide. See, Sanrio doesn't just throw random animals into the mix for the sake of it. Every single "critter" in Kitty White’s orbit has a specific backstory, a distinct personality, and a reason for being there. It's not just a collection of cute drawings; it's a massive, interconnected web of friendships that has been expanding since 1974.
Honestly, it’s a bit overwhelming. You have the London-based family, the school friends, and then the "pets" that are somehow also characters in their own right. If you’ve ever looked at a sticker sheet and wondered why there’s a sheep, a mouse, and a hamster all hanging out in a suburban backyard, you aren’t alone.
The White Family Foundation
Before we get into the more obscure critters, we have to talk about the core unit. Hello Kitty isn't a cat—Sanrio famously clarified she's a little girl—but her world is populated by characters that definitely lean into animal archetypes.
Her twin sister, Mimmy, is the one wearing the yellow bow on her right ear. This is the easiest way to tell them apart, yet people mess it up constantly. Mimmy is the shy one. She’s the domestic heart of the duo, often found embroidery-deep in a project while Kitty is out adventuring. Then you have George and Mary, the parents. George is your classic hardworking dad who loves his pipe, and Mary is the kind of mom who spends her days baking the legendary apple pies that Hello Kitty measures her weight in. (Five apples high, three apples heavy—classic Sanrio trivia).
Anthony and Margaret, the grandparents, bring that old-world charm to the Hello Kitty critter guide. Anthony draws, and Margaret spends her time in a rocking chair, knitting. It’s a very specific, cozy British aesthetic that Sanrio creator Yuko Shimizu leaned into because British culture was incredibly trendy in Japan during the early seventies.

The Schoolyard Critters You See Everywhere
Joey is basically the MVP of the friend group. He’s a blue mouse, and he’s faster than everyone else. If there’s a track meet in a Sanrio cartoon, Joey is winning it. He’s the guy everyone wants on their team.
Then there’s Fifi. She’s a sheep. But she’s not just a sheep; she’s the talkative, energetic one who usually ends up leading the pack when Kitty is busy. Fifi is that friend who always has a plan, even if that plan is just "let's go get snacks."
- Tiny Chum: He’s a teddy bear, but he’s treated like one of the kids. His backstory is actually quite sweet—he was a gift from Kitty’s father, and now he just hangs out with the gang.
- Tracy: A raccoon who is basically the class clown. He’s energetic and a bit of a prankster.
- Cathy: A quiet little bunny. She’s often seen as the most polite member of the group.
- Tippy: This is a strong bear who has a massive crush on Kitty. It’s one of those unrequited childhood things that adds a layer of "oh, that's cute" to the whole dynamic.
Rory is a squirrel who lives in the forest but frequently pops into the city to hang out. He's the one who teaches the others about nature. Without Rory, the group would be totally lost the second they stepped off the pavement.
Charmmy Kitty vs. Hello Kitty
This is where the Hello Kitty critter guide gets weirdly meta. Hello Kitty is a girl, but she has a pet cat. Her name is Charmmy Kitty.
Charmmy is a white Persian cat. She was a gift from Kitty’s father, George. If you’re confused, think of it like Mickey Mouse (a mouse) having Pluto (a dog) while Goofy (also a dog) walks around in pants. It’s just how cartoon logic works. Charmmy is much more "cat-like" than Kitty; she loves shiny things and wears a lace-edged bow that Kitty gave her.

She also has a pet of her own—a djungarian hamster named Sugar. Sugar was a gift from Dear Daniel, Kitty’s boyfriend. So, to recap: A girl (Kitty) has a cat (Charmmy), and the cat has a hamster (Sugar). It’s layers of cuteness that shouldn't work but somehow does.
Dear Daniel and the Expanded Universe
You can't talk about the inner circle without mentioning Daniel Star, better known as Dear Daniel. He’s been Kitty’s childhood friend and sweetheart forever. He went off to Africa with his photographer father for a while, which gave his character a bit of a "worldly" vibe when he returned to London. He’s a sentimental guy who loves dancing and photography.
The Forest Friends
Beyond the urban setting of Kitty’s house, there’s a whole ecosystem of forest critters.
- Thomas the bear: He’s the active one, always on a unicycle.
- Mory: A seal who just sort of appears sometimes.
- Tim and Tammy: A pair of monkeys who are constant sources of chaos.
These characters don't get as much screen time as Joey or Fifi, but they are essential for the "world-building" that Sanrio has perfected over five decades. They represent the idea that Kitty is friendly with everyone, regardless of species or background.
The Design Evolution
In the early days, the Hello Kitty critter guide was very minimalist. Thin lines, primary colors, very little shading. As we moved into the 80s and 90s, the "critters" started getting more detailed. This was partly due to the influence of Yuko Yamaguchi, the third designer for Hello Kitty, who is credited with giving the brand its modern staying power.
She realized that for Kitty to stay relevant, her world had to grow. This meant introducing characters that appealed to different demographics. Suddenly, the critters weren't just background noise; they were collectible icons. This is why you’ll see specific "eras" of side characters. Some, like the little mouse Joey, are timeless. Others feel very "of their time," reflecting the fashion and sensibilities of the decade they were introduced.
Why the Sidekicks Matter
Most people think the side characters are just filler. They’re wrong. The sidekicks are what give Hello Kitty her "humanity." Because Kitty herself is often a blank slate—no mouth, neutral expression—we understand her emotions through how her friends react to her.
When Fifi is excited, we know the group is having fun. When Mimmy is worried, we know there’s a problem. These critters act as the emotional signposts for the audience. They provide the context that Kitty, by design, leaves open to interpretation.
It’s a brilliant bit of psychological marketing. By surrounding a "neutral" lead character with a vibrant, specific cast of critters, Sanrio allows fans to project themselves onto the story while still having specific characters to latch onto. You might not be a "Hello Kitty," but you might definitely be a "Tracy the Raccoon."
How to Start Your Own Collection
If you're looking to dive into the world of Sanrio critters, don't just buy the first thing you see. Look for the "Golden Age" merch from the late 90s if you want the classic aesthetic. If you prefer the modern, sleek look, the current collaborations with brands like Baggu or Stoney Clover often feature the deeper cuts of the character roster.

Actionable Steps for the Aspiring Collector:
- Identify Your Favorite: Don't just go for Kitty. Look into the backstories of the "Schoolyard Friends" like Joey or Cathy. Identifying with a niche character makes the hobby more personal.
- Check the Bows: Remember the Mimmy rule. Yellow bow on the right ear is Mimmy. Red on the left is Kitty. If you find a vintage item where the bow is "wrong," it might be a rare manufacturing error or a bootleg.
- Visit a Sanrio Store: If you’re lucky enough to be near a flagship store (like the ones in Tokyo or Los Angeles), look for the "Character Ranking" displays. Sanrio holds a yearly vote where fans pick their favorite characters. Seeing where the "critters" rank tells you a lot about current trends.
- Study the Year of Origin: Knowing when a character was introduced (like Dear Daniel in 1999) helps you verify the authenticity of vintage "deadstock" items.
- Look for the Sanrio "Small Gift, Big Smile" Seal: Every official product should have it. If the artwork of the sidekick looks slightly "off," it probably is. Official Sanrio art follows very strict style guides regarding line weight and eye placement.
The world of Sanrio is far deeper than a simple red bow. It's a massive social network of animals, humans, and whatever Tiny Chum is, all coexisting in a world where the biggest problem is usually who ate the last slice of apple pie. Use this guide to navigate your way through the fluff and find the characters that actually speak to you.
