 From the UK's Royal Veterinary School says, hippos can fly briefly. While running at high speed, hippos are able to lift their bodies off the ground and fly for 0.3 seconds. And before you say, well, that's not very long, ask yourself, when's the last time you picked up a Chevy Blazer and held it in the air for 0.3 seconds? See? I don't know a lot about a lot of things. Let's just leave it at that. But I think that's jumping.
