I actually am not sure why I like hippos and rhinos. I think it is because they are the animals I see the least (like on animal planet shows, etc). I just think they are large, magnificent creatures that are fun to watch. I feel the same about elephants, but I have been exposed to elephants more than hippos (I even rode one once!).

I am not sure which would win in a fight. That would be one scary fight. Although I can't really imagine a hippo fighting.
