It's a tale that's just about as old as the internet: An unusual and adorable animal has captured the world's heart and become a viral online star. Remember April the giraffe, who delivered her baby on a live webcam back in 2017? (RIP, sweet mama -- April passed in 2021.) This time, it's a baby pygmy hippopotamus living at a zoo in Thailand. Moo Deng has a livestream where people worldwide can watch the cheeky hippo whenever they want. 

Here's everything you need to know about this chubby cutie -- and check out all our favorite Moo Deng memes, too.

Who is Moo Deng, and how did she go viral?

Moo Deng is a female pygmy hippo born in July at the Khao Kheow Open Zoo in Chon Buri, Thailand. Moo Deng is the seventh baby born at the zoo to her mother, Jona, who is 25 years old, and her father, Tony, who is 24, the Independent reports. Pygmy hippos can live to be 50 but are an endangered species, with only 2,000 to 2,500 adults in existence.

The Times reports that while zookeeper Atthapon Nundee began sharing Moo Deng on social media right away, the attached video now has more than 2.6 million views. The zoo held a Facebook poll to name her. 

What does 'Moo Deng' mean?

Moo Deng's popularity really took off when content creator Yammi Saracino translated the naming poll into English and shared it on social media.

Moo Deng, which The New York Times says translates to "bouncy pork," easily beat out Moo Sap ("minced pork") and Moo Daeng ("red pork"). The Independent says Moo Deng is a kind of meatball, which is equally great as a name for this little meatball.

Why do people love Moo Deng so much?

Have you seen her? The roly-poly little viral star is just fun to look at. She's mischievous too; she's teething so she likes to nip at her keeper. She's also still a baby, which leads to fun welcome-to-the-world videos, such as one showing her learning how to walk up a slanted edge of her pool.

You'll see her in plenty of memes. Just as with the dearly departed Grumpy Cat and other famed internet animals, it's easy to slap a caption on a photo of Moo Deng that depicts her dealing with life as we do. BuzzFeed even has a Moo Deng AI image generator that puts her into all kinds of situations, such as becoming president or eating a Dole Whip at Disney World.

How can I watch Moo Deng living her best life?

There's a 24/7 webcam in the hippopotamus section at the zoo where Moo Deng lives. (You may need to scroll down and click on the "Live Streaming" tab.) Bear time zones in mind; you may check it in the afternoon where you are and find out it's dark and quiet in Thailand, with no animals visible.

If there's nothing to watch when you tune in, the zoo is also sharing recorded livestreams of Moo Deng on its YouTube channel.

Plus, the Associated Press streamed an hour of Moo Deng cuteness on Sept. 19, and you can watch that on YouTube.

Moo Deng merch: The face that launched 1,000 products

Moo Deng's global popularity has inspired a line of official merchandise that's being sold by Khao Kheow Open Zoo, including stylish pants and a button-down shirt, as well as T-shirts that sold out quickly. 

If you missed out on scoring an official piece of merch, a quick Google search shows that you can find unofficial Moo Deng shirts being sold on everything from Amazon to Etsy and everywhere in between -- though presumably waiting for the restock to buy directly from the zoo will support Moo Deng's lifestyle.

You can find Moo Deng plush toys, Moo Deng T-shirts, Moo Deng costumes, Moo Deng pants, Moo Deng pajamas, Moo Deng hats, Moo Deng mugs -- and basically anything else your hippo-loving heart desires. There's even Moo Deng crypto.

How to watch Pesto the penguin

If you prefer flightless aquatic birds to pygmy hippos, you can follow Pesto, the 9-month-old baby king penguin at the Sea Life Aquarium in Melbourne, Australia. At 48 pounds, Pesto is bigger than many adult penguins already and eats 25 fish a day to stay that way.

"Pesto is the besto!" the aquarium brags on its webpage.
