What began as a quiet birth in a Thai zoo has turned into an international celebration. Moo Deng, the pygmy hippo born on July 10, 2024, at the Khao Kheow Open Zoo, marked her first birthday with a four-day extravaganza that captured the hearts of fans worldwide.
The party, held from July 10 to 13, 2025, was more than just cake and confetti — it was a cultural moment, a viral media event, and a charity-driven success story all rolled into one.
From Zoo Baby to Internet Icon
Moo Deng, whose name loosely translates to “bouncy pig,” became an instant sensation just months after her birth. With her soulful eyes and playful personality, she quickly garnered a fanbase across Thailand and beyond. Her daily antics were posted on social media, racking up millions of views and even inspiring a meme coin on the Solana blockchain.

A Birthday Worth Roaring About
The zoo pulled out all the stops for Moo Deng’s big day. A hippo-shaped birthday cake, crafted by a local patisserie, was the centerpiece of the event and auctioned off for charity — fetching a whopping 100,000 baht. Proceeds from the auction were donated to animal care initiatives at the zoo.
The birthday bash featured:
A photo exhibition documenting Moo Deng’s first year
A mascot parade with hippo-themed characters
Limited-edition Moo Deng merchandise, including plush toys, shirts, and collectible pins
Free entry for children under 135 cm or below the age of 12
Celebrity appearances by Thai entertainers and animal influencers
Charity auctions for exclusive Moo Deng memorabilia
Families, influencers, conservationists, and curious tourists all flocked to the event, creating one of the busiest weeks in the zoo’s history — with attendance quadrupling during the celebration.
A Diplomatic and Digital Celebration
The party also crossed international lines. The U.S. Embassy in Bangkok sent Moo Deng a plush hippo named “Sammie” as a birthday gift — a soft diplomatic gesture timed to coincide with America’s own Independence Day.
Meanwhile, Moo Deng’s rising fame spilled into the world of crypto. Her Solana-based meme coin saw a spike in trading volume around her birthday, with online communities speculating whether the hippo could become the next viral crypto mascot.
More Than Just a Cute Face
Beyond the buzz, Moo Deng’s birthday bash underscored important messages around animal welfare and responsible zoo tourism.
Increased foot traffic brought attention — and scrutiny. The zoo was quick to implement crowd-control measures, including a five-minute viewing limit per group and additional security. These measures followed past incidents of guests disturbing Moo Deng in hopes of triggering cute reactions.
The celebrations also played a vital role in fundraising. Merchandising and auction proceeds were funneled into sustainable care programs for endangered species, making Moo Deng not just a mascot, but a beacon for conservation funding.
Looking Ahead
As Moo Deng turns one, she’s no longer just Thailand’s beloved baby hippo — she’s a symbol of how a single animal, with the help of storytelling, social media, and a touch of whimsy, can spark global conversation and meaningful change.
With plans already in the works for an annual “Moo Deng Day,” Bangkok may have just found its newest — and furriest — national treasure.
