We could probably get by with saying "use rhino stats, but reduce land peed to 20 ft., give it a swim speed of 20 ft., replace gore with bite, and replace powerful charge with the hold breath ability of a crocodile". If we want to take it a step further, we could add "change feats to Alertness, Improved Bull Rush, and Power Attack".
