Giant Hippopotamus
These huge animals are very aggressive, and have been known to charge and attack humanoids, as well as capsize boats and kill those who are thus plunged into the water. Hippos are very strong, and very heavy. They weigh an average of 3d100+3,000 pounds, with bulls being larger than cows. Even normal hippos have a 75% chance to successful capsizing river boats, a 90% chance of capsizing smaller boats (canoes, rafts, rowboats, and the like) and a 50% chance of capsizing larger vessels. Giant hippos have a +20% chance to do the same. On a critical hit, in addition to any other effects, a hippo can swallow a human -sized target whole with its bite (Luck check to negate). The target is at -2d to all rolls while within the hippo’s gullet, and can only use small items it already had in hand. Swallowed victims take 1d3 damage each round from normal hippos, and 1d6 damage from giant hippos. Giant hippos are capable of scoring a critical hit on a 19 -20. A typical group is a single bull and 5d6 cows. They live 3d10+35 years. Giant hippos – sometimes called behemoths – are monstrously large, weighing four times as much as a normal hippo and being twice as large. Giant hippos live ten times as long as their smaller kin.
