Hippos do not have any special appendages. The animals have four legs and a tail. They do, however, secrete a red sweat that acts as a skin protectant and bug repellent.

The hippos diet consists of plant matter, so it is considered herbivorous. Hippos will eat any vegetable they can find although most are not easy to come across in the wild. However, hippos can and will eat meat. Also, (as a joke) in the movie The Librarian, hippos likes to candy bars too.
