Hippopotamus, you mean those cut-, littl-, lovel-, you got me. They're simply horrible. One does not use the words "Hipoptamus", and "cute" in the same sentence. Because they're not. If you have never seen a Hippo in real life, here's a picture of one.
I lied, here's about eleven. Enjoy.
As you can see, they look like giant water pigs. Not really appealing. The average hippo can weigh 3650 pounds. If you stack 6 Hippos together, you'll have the weight of a bus. (Although, older male hippos can weigh almost 10,000 pounds.) They can become 11 to 17 feet long, which is almost as long as four people lying down toe to face on the ground.
