Honestly, if you walked into a gift shop ten years ago and saw a plastic creature defecating a spectrum of light, you might have called the manager. Today? It’s a billion-dollar aesthetic. The image of a unicorn pooping a rainbow has shifted from a weird, niche internet joke into a massive cultural pillar that defines how we handle irony, marketing, and even our bathroom habits. It’s everywhere.
We see it on t-shirts, in viral commercials, and as the "star" of high-end toy aisles. But why? Why did this specific, somewhat gross imagery become the go-to symbol for modern whimsy?
The Squatty Potty Spark
You can’t talk about this without mentioning the 2015 marketing campaign that changed everything. Before Squatty Potty released their viral ad, the idea of a unicorn pooping a rainbow was mostly relegated to underground digital art or random Tumblr posts. Then came the prince. And the ice cream.
The Harmon Brothers agency took a huge risk. They used a mechanical unicorn to demonstrate—quite literally—the benefits of proper "elimination" posture. They didn't use brown sludge. They used bright, multi-colored soft-serve. It was genius because it bypassed the "ick" factor of talking about bowel movements while making the visual impossible to forget.
The numbers are actually staggering. That single ad campaign racked up over 100 million views and boosted sales by 600%. It proved that people weren't just okay with the juxtaposition of the majestic and the mundane; they craved it. It was the first time "unicorn poop" became a household term.

Unicorns are historically symbols of grace, divinity, and untouchable beauty. In medieval tapestries, they represent Christ or untamable nature. By making them do something as human and "dirty" as pooping, we are participating in a collective act of irony. It’s funny because it shouldn't be happening.
Psychologists often point to "benign violation theory" here. For something to be funny, it has to violate a norm, but in a way that feels safe. A unicorn pooping a rainbow is a perfect violation. It breaks the "sacred" rules of the mythical creature, but replaces the "gross" reality with something sparkly and colorful. It's safe. It's cute. It's weirdly comforting.
The Slime and Toy Industry Takeover
If you have kids, or if you've been in a Target lately, you’ve seen the "Poopsie Slime Surprise" line by MGA Entertainment. This wasn't some accidental hit. It was a calculated move into the "unboxing" and "collectible" market that dominates YouTube.
The toy is literally a doll you feed, and then it "poops" slime.
- It taps into the sensory trend of ASMR.
- It utilizes the "blind bag" gambling mechanic kids love.
- It leans heavily into the rainbow-poop aesthetic to make it "collectible" rather than "gross."
Isaac Larian, the CEO of MGA, has been vocal about following trends that bridge the gap between "nasty" and "cute." This is a market segment sometimes called "el-nasty" or "gross-out cute." It works because it feels rebellious to children but remains marketable enough for parents to buy.
The Digital Language of Emojis
We have to talk about the 💩 emoji. Originally, in the Japanese carrier systems like SoftBank, it was just a pile of dung. When it hit the global stage via Apple and Google, it took on a life of its own.

People started combining the unicorn emoji 🦄 with the poop emoji 💩. The tech world noticed. Suddenly, third-party sticker packs were flooded with variations of the unicorn pooping a rainbow. It became a shorthand for "this situation is bad, but I'm making it fabulous."
It is digital resilience in a nutshell.
Is It Just a Fad?
Most trends die within 18 months. This one has lasted a decade.
The reason it sticks is its versatility. You’ll find this imagery in pride parades as a symbol of joy and defiance. You’ll find it in Silicon Valley as a mascot for "Unicorn" startups (companies valued at over $1 billion) that are trying to prove they can do the impossible.
It’s also deeply rooted in the DIY "slime" culture that exploded on Instagram and TikTok. Creators like Karina Garcia built empires by mixing glitter and glue to create "unicorn poop" textures. This created a feedback loop: more content led to more demand for physical products, which led to more memes.
Cultural Nuance and Global Reach
Interestingly, the reception varies. In some cultures, the idea of playing with "poop" imagery—even rainbow-colored—is still a bit of a bridge too far for the mainstream. But in the US and UK, the "kawaii" influence from Japan (think Gudetama or Aggretsuko) has primed us to love things that are simultaneously pathetic, gross, and adorable.
The Science of Rainbows and Dopamine
There’s a biological reason we can’t look away. Bright, saturated colors—specifically the full spectrum—trigger a dopamine response in our brains. We are wired to seek out variety. When you combine that color hit with the humor of a unicorn pooping a rainbow, you’re getting a double-whammy of neurochemical rewards.
It’s "dopamine decor" in its purest, strangest form.
Real-World Applications You Didn't Expect
- Medical Education: Some pediatricians use the "rainbow poop" concept to talk to kids about digestion without scaring them.
- Confectionery: The "Unicorn Poop" cookie recipe (basically multi-colored sugar cookie dough dropped in scoops) remains one of the most searched-for party food items on Pinterest.
- Graphic Design: It serves as a case study in "Vaporwave" and "Retrowave" aesthetics, using neon pinks and blues to evoke 80s nostalgia.
How to Use This Trend Without Being Cringe
If you’re a creator or a brand, you can't just slap a rainbow on a horse and call it a day. The "Peak Unicorn" era of 2017 has passed. To make it work now, you have to lean into the absurdity.

Don't be "precious" with it. The most successful versions of the unicorn pooping a rainbow today are the ones that are slightly self-aware. They acknowledge that it's a ridiculous concept.
Think about the "Deadpool" approach. It’s gritty, it’s weird, but it uses the unicorn as a mascot for the bizarre. That’s the lane that still has traction.
Your Practical Next Steps
If you're looking to integrate this aesthetic into a project or just want to enjoy the trend, start by looking at the color palettes used by brands like Squatty Potty or Poopsie. They don't just use any colors; they use high-contrast neons.
Next, check out the "Unicorn Poop" DIY community on platforms like Pinterest to see how the textures are achieved—usually through a mix of pearlescent pigments and "fluffy" textures.
Finally, recognize that this trend is a tool for "pattern interruption." In a world of boring, beige corporate branding, a unicorn pooping a rainbow is the ultimate way to make someone stop scrolling. Use it sparingly, use it ironically, and most importantly, don't take it too seriously. It’s supposed to be fun.
Stop worrying about whether it's "professional" and start looking at why it works: it’s memorable, it’s colorful, and it makes people laugh. That is the triple threat of modern content.
