Choose your starter animal

When you initially start playing, you can pick one out of the four animals to start out as. Depending on which animal you choose, you may spawn in a different "biome". For instance, choosing the Mouse, you'll spawn on grass. Choosing the Shrimp will spawn you in the ocean.

Objective

Once you've selected one, your goal is to evolve to be the biggest animal you can be!

You can achieve this by eating the red dots or food items around the map to grow. You will earn XP and you should see an experience bar at the bottom of your screen to let you know when you can evolve.

Also, keep in mind that you do also need water, which you can consume the blue dots or by swimming in water.

Look out for other players bigger than you, they can eat you and you will have to start over! Good luck!
