Baby hippo Moo Deng becomes internet sensation

"It was beyond expectation," Atthapon told The Associated Press. "I wanted people to know her. I wanted a lot of people to visit her, or watch her online, or leave fun comments. I never would’ve thought (of this)."

Moo Deng, which literally means "bouncy pork" in Thai, is a type of meatball. The name was chosen by fans via a poll on social media, and it matches her other siblings: Moo Toon (stewed pork) and Moo Waan (sweet pork). There is also a common hippo at the zoo named Kha Moo (stewed pork leg).

"She’s such a little lump. I want to ball her up and swallow her whole!" said Moo Deng fan Areeya Sripanya while visiting the zoo Thursday.

Already, Moo Deng has been made into memes. Artists are drawing cartoons based on her. Social media platform X even featured her in its official account’s post.

With all that fame, zoo director Narongwit Chodchoi said they have begun patenting and trademarking "Moo Deng the hippo" to prevent the animal from being commercialized by anyone else. "After we do this, we will have more income to support activities that will make the animals’ lives better," he said.

"The benefits we get will return to the zoo to improve the life of all animals here."

The zoo sits on 800 hectares of land and is home to more than 2,000 animals. It runs breeder programs for many endangered species like Moo Deng's. The pygmy hippopotamus that's native to West Africa is threatened by poaching and loss of habitat. There are only 2,000-3,000 of them left in the wild.

To help fund the initiative, the zoo is making Moo Deng shirts and pants that will be ready for sale at the end of the month, with more merchandise to come.

Narongwit believes a factor of Moo Deng's fame is her name, which compliments her energetic and chaotic personality captured in Atthapon's creative captions and video clips.

Appropriately, Moo Deng likes to "deng," or bounce, and Atthapon got a lot of cute and funny moments of her giddy bouncing on social media. Even when she's not bouncing, the hippo is endlessly cute — squirming as Atthapon tries to wash her, biting him while he was trying to play with her, calmly closing her eyes as he rubs her pinkish cheeks or her chubby belly.

Atthapon, who has worked at the zoo for eight years taking care of hippos, sloths, capybaras and binturongs, said baby hippos are usually more playful and energetic, and they become calmer as they get older.

The zoo saw a spike in visitors since Moo Deng’s fame — so much that the zoo now has to limit public access to the baby's enclosure to five-minute windows throughout the day during weekends.

Narongwit said the zoo has been receiving over 4,000 visitors during a weekday, up from around just 800 people, and more than 10,000 during a weekend, up from around 3,000 people.

But the fame has also brought some hostile visitors to Moo Deng, who only wakes up ready to play about two hours a day. Some videos showed visitors splashing water or throwing things at the sleeping Moo Deng to try to wake her up. The hippo pit now has a warning sign against throwing things at Moo Deng — posted prominently at the front in Thai, English and Chinese.

Narongwit said the zoo would take action under the animal protection law if people mistreat the animal. But clips emerged of people treating Moo Deng poorly, and the backlash was fierce. The zoo director said that since then, they haven’t seen anyone doing it again.

For fans who can't make the journey or are discouraged after seeing the crowds for Moo Deng, the Khao Kheow Open Zoo set up cameras and plan to start a 24-hour live feed of the baby hippo in the coming week.
