Surprise was born in November 1993, the daughter of Abe and beautiful Bob. She has had 6 calves, the first one born when Surprise was very young just five years of age. Surprise is very easy to recognize as she is the biggest female hippo, looking at times more like a bull or a small rhino. I would say she weighs about 2 tons. She also has a very wrinkled skin and looks older than she is.
