Three eggs at start:
At the start of a game you will find a strange machine on the right which will warp you up. Ride to the second floor if you use the elevators, then go left as far as possible until you find another strange machine which you ride to the top of a tree. At the top of the tree you will find three eggs which you put under the tree and they will hatch.

Activate any item or machine:
To activate any toy or button press L when you are near them.

Quick Mating:
When the eggs have evolved to teens or adults use the red fruits which are found near the warp machine to make the males and females want to mate. The female will eventually lay an egg and the plants will grow back.

Poisonous/Safe Plants:
The mushrooms and plants on the second floor near the teleporter are poisonous and should never be eaten because of the side effects they cause like making the creatures not want to mate. The plants on the first floor where you start are safe and are very helpful.
