A massive head breaks the surface of the water, followed by a thick neck and a set of broad shoulders, all covered in thick dark grey hide. The figure rises up and up, higher and higher out of the river, water pouring off of its colossal form in streams as you look on in petrified awe, finally getting a good look at the.... hippo?!
Yes, standing up to its waist in the river is an anthropomorphic hippopotamus. As it steps out of the river, water still dripping down its massive form, you realize just how massive it is; at least 10 or 11 feet tall. What's more, it's, well, very much a female.

...Oh, shit.
You turn and try to run, but the hippo charges towards you with a burst of shocking speed. Oh, right - hippos can outrun horses in short bursts. Now trapped, you look up nervously at the titanic woman, while she looks down on you, her eyes positively gleaming with....
