All the various creatures drawn by everyone live in a three-dimensional space consisting of slopes with varying elevations. Color in a creature on the paper provided, and see the picture you have drawn come to life and move in front of you.

Living things eat each other and are eaten by each other in one shared ecosystem.

The creature you draw will multiply if it eats other living things, but it will die and disappear if it does not eat enough, or if it is eaten by other creatures.

The salamander eats the snakes, the snakes eat the lizards, the lizards eat the frogs, and the frogs eat the butterflies, each one propagating as they consume. Likewise, the butterflies multiply in places where flowers grow.

Although flowers will bloom if people stay still, their petals will scatter if people walk around and step on them. Salamanders will die if people step on them too much as well.

In this world, living things propagate and disappear - you might find the creature you drew, multiplying somewhere.
