Hippos are REALLY Dangerous! They get people on their backs and then jump them up so high into the air that they get really scared AND THEY DIE. And THAT is why a hippopotamus is kinda dangerous.
But you CAN HIDE from a hippopotamus. They don’t ever look for people behind their backs, behind bushes. So, yeah. You CAN hide. Don’t worry.
