A super sized birthday

CAMDEN, N.J. (WPVI) -- You can call them Party Animals, as the Adventure Aquarium celebrated Genny the Hippo's 17th birthday.

Dozens of party goers lined the Hippo Haven as a special cake made of watermelon and vegetables was laid in place for the big surprise.

Moments later out came Genny to enjoy her vegan sweet treat as visitors sang happy birthday.

A porcupine friend even got in on the action and helped Genny eat her cake.

And look at this, a large driver's license cake was made with Genny's face on it as she turned 17.

Her height and weight of 4,000 pounds was also listed.
