What to become a Hippopotamus? Then we've got a great range of Hippo costumes, for adults and kids. Hippo fancy dress is a great sub category, if you are looking to dress up as an animal. These wild mud beasts are found in sub-Saharan Africa, but we've brought the animal to you, in the form of our Hippo outfits. These huge beasts spend most of their day cooling off in the lakes and rivers, so our outfits are pretty cool too, regardless of whether you are shopping for men, women, boys or girls. Whether you want to wear one of our full hippo costumes, or would rather just a few accessories, we have it all here in one place. Be sure to check out our other animal costumes for more ideas.
