Capsize (Ex)

A submerged dire hippo that surfaces under a boat less than its space can capsize it by making a CMB check. The DC of this check is 10, or the result of the boat pilot’s Profession (sailor) check, whichever is higher. For each size category the boat is larger than the dire hippo’s size, the dire hippo takes a cumulative –10 penalty on this CMB check.

Hold Breath (Ex)

A dire hippo can hold its breath for a number of rounds equal to 5 times its Constitution score before it risks drowning.

Template Base Dire Creature

Dire hippos resemble their smaller cousins and grow up to 20 feet long and can weigh up to 10,000 pounds.

Dire hippos gave rise to the legends of the behemoth, a massive beast that can drink entire rivers, and make the earth tremble when it walks. Although they can’t quite drink it all, dire hippos are the undisputed masters of the river in which they reside. All predators give them a wide berth.
