The internet has fallen in love with Moo Deng, a two-month-old pygmy hippo who lives in Thailand’s Khao Kheow Open Zoo.

Why? Who’s to say? Maybe it’s her tendency to howl at the slightest inconvenience; maybe it’s all of the relatable videos of her biting the people trying to take care of her. Regardless, the people love her, and if you’ve been on X in the past week, you’ve more than likely seen her screaming face.

Recently, Moo Deng encountered a monkey. “How nice,” you might think. “What a great interspecies friendship!”

Well, hold that thought, because the altercation soon ended with the hippo being slapped.
