Hippo had 3 looks: original(brown), classic(purple), and new.
It's ability can randomly be larger than usual.
The Hippo is purple, with a purple snout and two darker purple nostrils. is has a solid triangle tail and light purple ears.
As of a recent update, Hippos got a new, more realistic look (they used to
be brown, see the image to the right).
The Hippo can move quickly in water and mud. If a predator tries to eat you, use your ability to escape. To hunt down prey use your ability. Rhinos and crocs are the best ones to hunt down. If you see a big croc that's almost a small rhino. If you see a big rhino that's almost about to evolve; don't let it evolve just use your ability!
As a hippo, it is good to stay in a lake since you are the fastest animal in lakes. It would be even better to go to bigger lakes with 2 islands (islands gives better food) or lakes with pear bushes around it (pears gives a lot of xp too). Be extremely careful when hunting in the ocean because Krakens would love to have a nice little hippo for breakfast...
If you are being chased by an elephant, go into a river and go against the river's current (hippos are immune to river currents but elephant get's pushed) and you can escape really easily.
