The hiphopopotamus, like trolls and hippopotamuses like rivers. Unlike these creatures however they are quite willing to leave their rivers when they sense it is being threatened. A centaur-like creature with a hippopotamus-like head and a four kangaroo like legs. The hero upon approaching a river, especially one which looks shallow enough to be forded, should be on the look out for this water hazard -- not for the water, but from the air. A mature adult with the help of its vestigial wings is able to leap into the air remarkably fast. As one is distracted by the waterspout created by its leap it is already descending down upon you. With its large feet it does not have to be very accurate. Like a cat it tends to play with the hero letting him/her escape momentarily to be stomped upon again and again, unless the hero plays dead (or dies) quickly.
