Tourists mistreat and toss objects at Moo Deng, the viral pygmy hippo, and the Thai zoo is threatening legal action.

"Moo Deng" is a two-month-old female newborn pygmy hippopotamus that has gained a lot of admirers all around the world thanks to her adorable and plump appearance.

Moo Deng is housed in a zoo in the Thai province of Chon Buri.

But because of her popularity, there are long lines at the zoo and unwelcome fan behavior; some have been seen hurling objects and splattering water at Moo Deng in an attempt to garner her attention.

The zoo will take appropriate action to stop animal abuse.

Narongwit Chodchoi, the director of the zoo, has asked visitors to be respectful of the animal after videos of tourists shoving things and splattering water on a sleeping hippo appeared online.

According to the BBC, Chodchoi said that the zoo has CCTV cameras all around the enclosures and vowed to take legal action against those who violated them.

Because of overpopulation, the zoo has also restricted the amount of time visitors can spend with the hippo.

The zoo posted on X that during weekends, guests are only allowed to view the hippos "per round" in order to maintain "safety and to allow all tourists to see" the hippos.
