Hippo is different. They will let this sweat form a film on their body to resist the exposure of the natural sun, maintain their skin color and prevent themselves from being sunburned. I later washed it in the water, so I thought he was pretty cool.
I believe I know this. If you see the hippo in the future, you won’t feel strange. They are just using this layer of sweat as their umbrella, can effectively prevent themselves from being sunburned, protect their skin, and their own body. Is it very clever?
