A New Arrival in Moo Deng's Family
A pygmy hippopotamus born on 4 November 2026 at Khao Kheow Open Zoo in Thailand's Chonburi province has made Moo Deng, the zoo's viral star, an aunt. The newborn is the offspring of Moo Deng's older brother, seven-year-old Moo Toon, and 14-year-old Moo Manao.

Natural Resources and Environment Minister Suchart Chomklin announced the birth on Thursday, 5 November. Zoo director Narongwit Chodchoi said veterinary checks found both mother and calf healthy, with the youngster already moving around and exploring while staying close to its mother.
The arrival follows a national zoo breeding initiative that brought the parents together in January 2025. Moo Manao moved from Nakhon Ratchasima Zoo, also known as Korat Zoo, to take part in the project, which aims to increase Thailand's pygmy hippopotamus population.
For followers of Moo Deng, the news brings another member of a familiar animal family into view. For the zoo's caretakers, the immediate task is watching over a mother recovering from birth and a calf beginning to explore its surroundings.
Mother and Calf Stay Close
Narongwit said veterinary staff had closely monitored Moo Manao and her calf after delivery. The two are living together normally, and the mother remains nearby as the newborn moves around their space.
Caretakers described Moo Manao as still exhausted after giving birth. She is also protective, keeping watch over her calf and showing reluctance to let staff approach closely. Suchart described that protectiveness as normal maternal behavior.
The calf has begun exploring despite remaining under its mother's watch. Those early movements, together with the veterinary health checks, form the zoo's first account of how the pair are doing after the birth.
Photos Bring the Newborn to Fans
Zoo caretakers shared photographs of the calf on Facebook, where the images quickly attracted attention. One showed the newborn resting with sunlight falling across its body. Another captured it mouthing its mother's cheek.
Photographs of Moo Deng as a young calf were also shared for comparison, giving followers a familiar reference as they looked at the family's newest arrival. More images followed as interest grew.
Moo Deng's connection to the calf is straightforward: Moo Toon is her older brother, making her the newborn's paternal aunt, meaning an aunt on the father's side. The calf belongs to the next generation of the same family.
The public response has so far centered on photographs and updates from caretakers. Those glimpses show the newborn beside Moo Manao while staff continue their observations at the zoo.
A Breeding Project With a Ceremonial Start
Moo Toon and Moo Manao were paired on 24 January 2025 under the national breeding initiative. Moving Moo Manao from Korat Zoo brought the two animals together at Khao Kheow, linking the work of two Thai zoos.
The pairing was also marked by a wedding ceremony. Princess Ubolratana Rajakanya attended as a senior relative of the groom and signed the pair's ceremonial marriage certificate as a witness.
The celebration gave the pairing a public occasion long before the calf arrived. Behind that event was a practical aim: bringing animals from different zoos together to produce offspring and increase the population cared for by Thailand's zoos.
The November birth is a new development in that project. It also connects two kinds of public interest around Khao Kheow: affection for Moo Deng and attention to the zoo's work breeding pygmy hippos.
From the Parents' Pairing to the Birth
The family's recent history spans two calendar years, beginning with the parents' pairing and ceremony in January 2025 and continuing with the birth and announcement in November 2026.
The dates in the Thai announcements use the Buddhist Era calendar. The year 2568 corresponds to 2025, while 2569 corresponds to 2026. Subtracting 543 gives the equivalent year in the Gregorian calendar used internationally.
- 24 January 2025: Moo Toon and Moo Manao were paired under the breeding initiative, with a wedding ceremony attended by Princess Ubolratana Rajakanya.
- 4 November 2026: Moo Manao gave birth to the calf at Khao Kheow Open Zoo in Chonburi.
- 5 November 2026: Suchart announced the arrival and shared the zoo director's update that mother and calf were healthy.
The January date marks the parents' pairing and ceremony. The zoo's account places the birth on 4 November, followed by the public announcement the next day.
When Will Visitors Meet the Calf?
Khao Kheow Open Zoo plans to introduce the newborn to visitors soon, while caretakers continue assessing when it will be ready. At the announcement, no public viewing date had been given, the calf's sex had not been determined, and its name had not been announced.
Moo Manao's condition and her behavior around the newborn are part of the situation staff are monitoring. She is recovering from delivery, keeping the calf close and limiting how near caretakers can come.
Visitors hoping to see the youngster therefore have photographs to follow while the zoo prepares for an introduction. The immediate arrangement keeps mother and calf together as veterinary staff watch their health and the newborn becomes more active.
The next practical milestone is a confirmed public introduction. Until then, the central update is a simple one: the zoo says both animals are healthy, and the calf is already moving around beside its mother.
