Hint: Africa:
Put a fence around the entrance to the zoo so that the entire zoo qualifies as a cage. Then, cover the whole zoo in savana grass and add plants and lakes. Place some animals then walk around as a zoo keeper/guest. To do this faster, do not get staff, food/water dishes or shelters. It will look unnatural. If you put gazelles in a pack, only put about two to six of them or some might ditch the pack. If you encounter across a dirty animal, wash it or all the animals will get sick and die. Note: Plant eaters will get eaten.

Hint: Babies:
You do not need two animals to have a baby. Just adopt a female animal and wait for about a month. Then, adopt a male of the same species and place him in with the female. Do not do anything from the time that you adopt him until the female gets pregnant. When she does, select "Undo". That will undo the adoption of the male and your female will still be pregnant.

Hint: Make water deeper:
Choose the "Deep Water" tool, and use it as you normally would. Then, select the "Ditch" tool and use in the deep water you just created.

Hint: Monkey meat:
Make a small pen. Put meat eating animals in it and put a vulnerable herbivore in it. Eventually a carnivore will kill it and the herbivore will become a carcass of meat.

Hint: Successful freeform zoo:
Close your zoo when you first begin a new zoo so that no guests are unhappy while you are building it. First, put in two food stands, two drink stands, dessert stands, one restaurant, and one zoo exhibit before opening your zoo again. Guests also like donation boxes. Make sure three of your four walls are made with the hill device in the "Landscaping" section. The other wall should be made with a fence so that guests can see the animals. Set all of your prices low, including the admission price. Do not forget benches, restrooms, and ATMs. For entertainment, add photo souvenir stands, arches, playgrounds (make an area out of sand path and put your playground equipment on top), fountains and statues. Also put in picnic tables and gift shops. With any extra money, crate playgrounds or peacock exhibits with one male peacock. They are more beautiful and will amuse guests. Note: Make sure to fully close exhibits with natural walls. Sometimes animals can squeeze out and chase guests. Double-check the exhibits with big cats, grizzly bears, and elephants.

Glitch: Recycle bins:
Maintenance workers do not pick up recycle bin trash. You must do this yourself.
