Hippos are huge creatures, and they are definitely not meant to be trifled with – especially when they are in their element, which would be in a pool of water. Gentle giants, so to speak, but when one of them is enraged, you might want to watch out! Being so large in size when fully grown, you can also expect them to eat a whole lot, and I would suppose that this is the inspiration for the $12.99 Hungry Hippo Wall Pocket. This is one hippo whose looks does not lie, being more than ready to snack on your keys, accessories, neckties, and money, among others. Good thing it is not going to swallow them though!
