Thousands of excited fans flocked to a Thai zoo on Thursday to celebrate the first birthday of Moo Deng, the adorable baby pygmy hippo that has become a social media sensation.
The Khao Kheow Open Zoo was overrun with Moo Deng's fans on the first of four days of activities marking the hippo's birthday. Children under 12 years old can enter the zoo, which is about a two hour drive from the capital Bangkok, for free throughout the extravaganza.
