i heard about this on ellen. and i believe it might be the cutest thing ever. a hippo and tortoise were replaced after the tsunami into the chicago zoo. there wasnt' a lot of room for all of the misplaced animals so they placed the tortoise and the baby hippo together. now. they are in love and inseperable. some bad news, the hippo is acting like a tortoise. however, they are the best of friends. how really sweet!
