This is about 10 minutes after the keeper talk for the Hippos. Clearly the couple of carrots and avacado pieces were not enough to quench their big hippo hunger as they decided to go to TOWN on the tree that's in the middle of their exibit. When asked if they have shown this behaviour before, the keeper she had not seem them doing anything like this before and showed concern for them ripping the tree down. Eventaully they had their fiill and continued to forage on the ground, leaving the rest of the tree as a snack for another day.
