We've been to Adventure Aquarium a few other times, and have always been impressed with the hands-on, family-friendly exhibits, and Hippo Haven was no exception.
As you make your way to the lower level of the exhibit, you can sit and watch Genny and Button or watch a video about hippos.
Of course we had to stop and see Lizzie before we left, along with the other amazing displays of aquatic life throughout Adventure Aquarium.
