Moo Deng (Thai: หมูเด้ง, RTGS: Mu Deng, Thai pronunciation: [mǔː dêŋ]; born 10 July 2024) is a pygmy hippopotamus residing at Khao Kheow Open Zoo in Si Racha, Chonburi, Thailand.[1][2] She gained widespread attention as an internet meme at two months old, after photos of her went viral online in September 2024.

Background

[edit]

Moo Deng was born on 10 July 2024 to parents Tony and Jonah. She has two full siblings (Nadet and Moo Tun) and four half-siblings (Ko, Kanya, Phalo, and Moo Wan).[3] The name Moo Deng was chosen through a public poll, with over 20,000 people voting for it. It translates to 'bouncy pork' or 'bouncy pig' in English.[4][5][6][7]

Online popularity

[edit]
Thai-language news coverage of Moo Deng in September 2024

Khao Kheow Open Zoo posted images of its pygmy hippopotamuses on its official Facebook page, and Moo Deng quickly became a fan favorite.[8] Moo Deng is noted to be more playful and energetic than other hippopotamuses. In response to her popularity, the zoo began selling clothing and other merchandise featuring designs based on Moo Deng.[4][9][10] Moo Deng inspired many pieces of fan art.[11]

Due to Moo Deng's viral online popularity, the number of daily visitors to the zoo doubled in early September 2024.[12][13] Around this time, some visitors harassed the baby by splashing her with water[10][14] or throwing objects at her to wake her up. As a result, the Khao Kheow Open Zoo installed security cameras around her enclosure. The zoo director threatened legal action against visitors who harassed her.[15][16][14] The misbehavior by some visitors has been widely condemned online.[17][18] The zoo also implemented a five-minute time limit for visitors in order to accommodate the high volume.[19]

In September 2024, zoo director Nitwit Chodchoi announced that the zoo had begun the process of copyrighting and trademarking "Moo Deng the hippo" to raise funds for the zoo.[6][20] The zoo also plans to launch a continuous livestream to allow fans to watch Moo Deng live over the Internet.[21]

On 28 September, Moo Deng was the subject of a Saturday Night Live sketch.[22] She was parodied by Bowen Yang on Weekend Update, and the character was used to satirize American pop-artist Chappell Roan's commentary on fame and political endorsements.[23]

In November 2024, the zoo posted a video showing Moo Deng choosing between two carved fruit dishes featuring the names of Donald Trump and Kamala Harris in what the zoo said was a prediction on who would win the 2024 United States presidential election. Moo Deng selected the fruit engraved with Trump's name, a prediction that ultimately came true.[24][25] That same month, GMM Grammy released an official Moo Deng theme song composed by Mueanphet Ammara titled "Moodeng Moodeng!" in Thai, English, Chinese, and Japanese.[26][27] In December 2024, Google published a year-in-review-themed Google Doodle video about the most searched topics of that year, with Moo Deng featuring in it.[28][29]

In February 2025, the coordinator for the Taï Hippo Project in Côte d’Ivoire, Elie Bogui reported that while the meme has gone viral, there had been no significant impact observed in terms of funding for pigmy hippo conservation and protection.[30]

Over 69,000 fans visited the zoo on 10 July 2025 to celebrate Moo Deng's first birthday.[31]

Welfare concerns

[edit]

Animal welfare groups have expressed concern for Moo Deng. A spokesperson for People for the Ethical Treatment of Animals (PETA) said, "She faces a lifetime of confinement," while World Animal Protection said, "Sharing Moo Deng content might seem innocuous, but it promotes cruelty to animals."[32] The zoo's director, Narongwit Chodchoi, rejected the allegations and maintained that the facility ensures the welfare and quality of life for more than 2,000 animals.[32] The Thai Society for the Prevention of Cruelty to Animals said that Moo Deng was well taken care of and that PETA was relying on "outdated" information.[32]

Moo Deng is a Thai pygmy hippopotamus born on July 10, 2024, at Khao Kheow Open Zoo in Chonburi province, Thailand, renowned for becoming a global internet sensation and viral meme in late 2024 and 2025. Her name, selected through a public poll at the zoo, translates from Thai as "bouncy pork," capturing her playful, bouncy, and often chaotic personality. Videos and photographs posted by zoo staff showcased her sassy behavior, including persistent attempts to bite her caretaker's knee, resistance to being handled, and expressive reactions that blended cuteness with an untameable spirit, quickly propelling her to widespread fame across social media platforms. Often described as resembling a "moist potato" with the "iron will of a toddler," Moo Deng's authentic, impulse-driven antics and unapologetic demeanor resonated deeply with audiences worldwide, offering joy and relief during difficult times. Her popularity dramatically increased visitor numbers at Khao Kheow Open Zoo, drawing thousands of fans—including international visitors who traveled specifically to see her—and inspiring merchandise, memes, brand collaborations, and appearances in mainstream media such as a cameo on Saturday Night Live. As a representative of the endangered pygmy hippopotamus species (Choeropsis liberiensis), with fewer than 3,000 individuals estimated in the wild, her rise to fame has also drawn attention to conservation challenges facing these animals in West Africa.

Early Life

Birth

Moo Deng, a female pygmy hippopotamus, was born on July 10, 2024, at Khao Kheow Open Zoo in Si Racha, Chonburi Province, Thailand. The birth took place at the zoo's facilities, where she arrived as the latest addition to the resident pygmy hippopotamus group. She is the seventh offspring born to her parents at the zoo.

Parentage and Birth Circumstances

Moo Deng's mother is Jona, a female pygmy hippopotamus residing at Khao Kheow Open Zoo, and her father is Tony, a male pygmy hippopotamus also at the zoo. Jona gave birth to Moo Deng in the zoo's pygmy hippo enclosure without reported complications, and the calf was described as healthy and active shortly after delivery. Zoo staff monitored the birth process closely, consistent with standard care for pygmy hippos in captivity, and Moo Deng began nursing successfully from her mother. The parentage reflects the zoo's ongoing efforts to maintain a breeding population of this vulnerable species.

Naming

Moo Deng, born on July 10, 2024, at Khao Kheow Open Zoo, received her name through a public voting poll organized by the zoo. The name "Moo Deng" (หมูเด้ง) combines "moo" (หมู), meaning "pig" or "pork" in Thai, with "deng" (เด้ง), meaning "bounce" or "bouncy," translating to "bouncy pig" or "bouncy pork" in English. The zoo presented three name options for the public to vote on: Moo Deng, Moo Daeng, and Moo Sap. Over 20,000 participants took part in the poll, with the majority selecting Moo Deng as her official name. This choice continues a playful naming theme observed among her siblings, including Moo Toon ("stewed pork") and Moo Waan ("sweet pork").

Life at Khao Kheow Open Zoo

Habitat and Daily Care

Moo Deng resides in an enclosure at Khao Kheow Open Zoo in Chonburi province, Thailand, where she shares her living space with her mother, the 26-year-old pygmy hippopotamus Jona. The enclosure provides access to a water feature that allows her to splash and bathe, accommodating the semi-aquatic behavior typical of pygmy hippopotamuses. Her popularity led to large crowds and some visitor harassment incidents, such as pouring water on her or throwing objects. In response, the zoo limited viewing time (initially to 5 minutes per visit on weekends), increased security around the enclosure, and warned of legal consequences for mistreatment. The zoo has stated that it ensures the welfare of its animals, including Moo Deng. Daily care at the zoo includes regular feeding with fresh fruits and vegetables, suited to her dietary needs as a young pygmy hippopotamus. Keepers monitor her condition and provide meals, with additional enrichment through an interactive program called "Cook for Moo Deng," in which supervised visitors prepare food for her as part of the zoo's wildlife engagement efforts. On special occasions, such as her first birthday celebration, she has been presented with fruit-based treats. The zoo maintains ongoing veterinary oversight to support her health and development.

Behavior and Personality Traits

Moo Deng displays a highly playful demeanor typical of young pygmy hippopotamuses, frequently engaging in energetic bouncing and quick movements around her enclosure. She often bites the legs and hands of her keepers during interactions, a behavior the zoo describes as playful rather than aggressive, common in baby hippos exploring their environment and testing boundaries. The calf is frequently captured in videos showing wide yawns, side-eye glances, and what appear to be grumpy expressions, contributing to her distinctive sassy look despite her young age. In addition to active play, Moo Deng spends significant time napping in various positions, sometimes sprawled out or resting her head on objects, while her skin remains consistently moist and shiny due to regular water exposure and natural secretions essential for pygmy hippo health. These traits, documented through official zoo footage, highlight her combination of curiosity, high energy, and occasional apparent discontent that define her observable personality.

Rise to Fame

Initial Viral Videos

Moo Deng first gained viral attention in September 2024 through a series of videos posted by the Khao Kheow Open Zoo on its official social media accounts, primarily Facebook and Instagram, when she was approximately two months old. These clips, shared by zoo keepers, featured the young pygmy hippo displaying playful and mischievous behavior, including repeatedly biting her caretakers' legs during interactions and feeding sessions. The videos also captured her napping in curled-up positions and frolicking in her enclosure, highlighting her energetic and bold personality that quickly resonated with online audiences. The initial posts emphasized everyday moments at the zoo, such as Moo Deng's attempts to bite while being handled or during playtime, which were presented as endearing rather than aggressive. These short clips spread rapidly across social media platforms, accumulating millions of views and shares within days, as users reposted and reacted to her chubby appearance and feisty antics. The zoo's consistent posting of such content in September 2024 marked the beginning of her widespread online popularity, driven by the authentic and frequent updates from her caretakers.

Social Media Presence and Growth

Moo Deng's rapid rise to fame has been closely tied to her presence on social media, particularly through the official Instagram account @immoodeng, managed by staff at Khao Kheow Open Zoo. The account serves as the primary channel for sharing daily updates, photos, and videos of the baby pygmy hippopotamus, directly from her caretakers. Follower growth on @immoodeng accelerated dramatically following her initial viral exposure, with the account attracting a global audience drawn to her distinctive personality and appearance. Posts are updated frequently by zoo keepers, often multiple times per week, featuring content such as feeding sessions, playtime, and interactions with staff that sustain high engagement levels through likes, comments, and shares. This consistent activity has fostered ongoing audience expansion and interaction, building on the momentum from early viral videos while establishing @immoodeng as a key hub for fans worldwide to follow Moo Deng's development. The account's growth reflects the broader surge in interest in the zoo's social channels driven by her popularity.

Cultural Impact

Memes and Public Appeal

Moo Deng's distinctive blend of adorable pudginess and feisty personality propelled her to meme stardom, with her round, potato-like body and perpetually moist, glossy appearance becoming central to her viral appeal. Fans and meme creators embraced her as a "little bouncy meatball" or "sassy little meatball," often highlighting her chaotic, toddler-like energy through biting keepers, dramatic squirming during baths, and grumpy or screaming expressions that conveyed relatable frustration or defiance. Memes frequently portrayed her as "ungovernable" or a chaotic gremlin, with captions such as "mood" overlaid on her unimpressed stares, "potato" for her compact sleeping poses, or descriptions of her as a "lifestyle icon" defined by being "inexplicably moist at all times," "slightly blurry in most photos," and "probably screaming or sleeping." Other popular formats inserted her into iconic scenes, like The Shining hallway or Godzilla parodies, to emphasize her unpredictable and expressive nature, while her biting incidents inspired "chomp!" jokes that playfully downplayed her feistiness. This grassroots online enthusiasm translated into real-world devotion, exemplified by her first birthday celebration from July 10 to 13, 2025, at Khao Kheow Open Zoo, where thousands of fans gathered for a multi-day bash complete with crowds and global attention. The event underscored her status as a beloved figure whose mix of cuteness and attitude sustained widespread affection beyond the initial viral videos.

Merchandise and Commercial Products

Following her rapid rise in popularity, Khao Kheow Open Zoo introduced official merchandise featuring Moo Deng in late 2024. The initial line, launched in September and made available starting October 1, includes apparel such as T-shirts, button-up shirts with collars, and distinctive 80’s-style pants emblazoned with playful illustrations of the pygmy hippo. These items are sold exclusively at the zoo itself, with no online or international shipping options noted for the official collection. Inspired by Moo Deng's viral appeal, independent creators and sellers have produced a wide array of unofficial merchandise available on platforms such as Etsy, Redbubble, and Shopee. These include T-shirts with humorous or vintage designs, embroidered hats, stickers, posters featuring artistic parodies, and small collectible figurines depicting the baby hippo. Additionally, Moo Deng has been commemorated through an official theme song titled "Moodeng Moodeng," released in November 2024 by GMM Music, a major Thai music company, and produced by songwriter Mueanphet Ammara. This 50-second upbeat track is available in four languages—Thai, English, Chinese, and Japanese—and features simple, repetitive lyrics such as “Moodeng Moodeng deng deng deng” and “Please Mommy, come play with me / Bounce with me, Mom,” accompanied by looped footage of Moo Deng bouncing and playing. The song is distributed on YouTube, Spotify, and Apple Music, where its music videos quickly amassed over 100,000 collective views shortly after release.

Media References and Appearances

Moo Deng's viral success has attracted attention from mainstream media and entertainment programs. On September 28, 2024, Saturday Night Live's Weekend Update featured a segment in which comedian Bowen Yang humorously discussed the baby pygmy hippo's internet fame, her biting incidents with zookeepers, and her overwhelming popularity among fans. The appearance highlighted how her mischievous personality translated into late-night comedy. Major news outlets have published features on Moo Deng, often focusing on her role as a global internet phenomenon and the joy she brings to visitors at Khao Kheow Open Zoo. The Guardian ran a detailed profile on her rapid ascent to stardom and the social media frenzy surrounding her daily activities. NBC News covered her story, emphasizing her appeal across age groups and the zoo's efforts to manage crowds drawn by her fame. Other outlets, including PBS, have referenced her in segments about animal behavior and viral wildlife moments. Moo Deng has an entry on the Internet Movie Database (IMDb), which includes a biographical summary of her life and rise to prominence but lists no acting credits or formal media credits. This reflects her status as a cultural figure rather than a traditional media performer.

Controversies

Animal Welfare Concerns

Animal rights groups have raised concerns about the welfare of Moo Deng at Khao Kheow Open Zoo, particularly regarding her enclosure conditions and the effects of intense public attention. PETA has criticized the facility for exposing the young pygmy hippo to rowdy crowds who shout and throw objects at her from 8 a.m. to 5 p.m., during hours when she should be sleeping as a nocturnal and reclusive species. PETA further stated that Moo Deng has nowhere to hide and barely enough water to swim in, describing the arrangement as designed to entertain visitors rather than benefit her, with adult hippos at the zoo kept in barren plots. The group also condemned the zoo as unaccredited and accused it of breeding Moo Deng for profit rather than genuine conservation, predicting she will spend decades in a barren enclosure and die there without experiencing the diverse habitat and natural behaviors of wild pygmy hippos, such as hiding in rivers during the day and foraging at night. Other organizations, including Born Free, have urged the public not to visit Moo Deng or similar famous zoo animals, arguing that viral fame generates revenue for the zoo through increased ticket sales and donations but offers little conservation benefit while potentially harming individual welfare through heightened visitor presence. Born Free noted that increased crowds are likely to negatively affect pygmy hippos and highlighted that the zoo had to install CCTV, limit visitor numbers, and ask people to stop throwing objects or making loud noises to goad Moo Deng. In response to the criticisms, Khao Kheow Open Zoo director Narongwit Chodchoi rejected PETA's allegations, stating that the facility cares for over 2,000 animals and ensures their welfare and quality of life. The zoo has implemented measures to manage crowds and reduce disturbance, including limiting viewing time to five minutes per visitor and launching a 24-hour live stream for remote viewing. The zoo has also limited groups to 30 to 50 people per round to avoid overcrowding. Additionally, the Thai Society for the Prevention of Cruelty to Animals described PETA's assessment as based on incomplete, outdated, and inaccurate information, affirming that Moo Deng receives care at international standards. The zoo has positioned Moo Deng's presence as part of a conservation breeding program for the endangered pygmy hippopotamus species. Broader concerns about pygmy hippo captivity include arguments from groups like World Animal Protection that zoos do not effectively address wild population threats such as deforestation, hunting, and climate change, and that exhibiting individuals provides no measurable conservation impact.
