In Philadelphia and South Jersey, you can spend hours watching hippos noshing on pumpkins at the Philadelphia Zoo and Adventure Aquarium.

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).

Moo Deng has become a social media sensation, drawing crowds and raising awareness for endangered species conservation.
