Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the "zoo.ini" file in the game folder. Add the following entries under the "[scenario]" section.
-If the monkeys are put in an exhibit at ground level, occasionally the Chimpanzees will escape from their exhibit. It is is better if you lower the ground about two or three levels then put a wall on top next to the pavement. However, do not put it on the low ground. The monkeys won't be able to reach the fence to jump out. Do not put any trees close to the edges as they could climb the trees. You now will have an inescapable exhibit. This can also be done for other animals.
-To prevent monkeys from escaping, make the land higher than the normal height and do this until you can see the dirt. After that, they will not escape.
Block off part of the exhibit, then put terrain that can be trampled there. In their part of the exhibit, put Dirt, Sand, Brown or Gray Stone, or Snow. You can also use water as a fence if the animal cannot swim.
When your guests are looking at an animal from the side of an exhibit, immediately pause game play and build another exhibit around the guests. Place some lions or crocodiles in the exhibit and resume the game. The guests will start running around screaming.
For flying reindeer, name them after Santa's reindeer (Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, Blitzen) They will not fly all the time, but eventually stars will appear under their feet and they will glide across the exhibit.
Activate the following cheats by renaming your guests to the corresponding names:

Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the "zoo.ini" file in the game folder. Locate the following lines and change the values after the "=" as indicated. Note: The changes only affect new games and do not work on saved games.
Pause game play when you have plenty of guests, then block the zoo entrance with a brick fence or a statue. Delete all your zookeepers, then delete all the fences for the exhibits and resume the game. Your animals will start chasing your guests. Bears, tigers, lions and other carnivores are more aggressive and will literally throw your guests in the air when attacking.
Set your system date to October 31 or November 1 and all guests and buildings will turn orange and black. You can also purchase a jack-o-lantern at the buildings and items menu and see a witch fly overhead.
To get Panda Research you must complete the Breeding Giant Pandas scenario. You need to breed Giant Pandas, but you cannot get them until you make fifteen excellent exhibits. You also need to do all Panda Research and get their cave and bamboo. You can then get only two pandas, one male and female. To raise your chance of breeding your pandas, build their exhibit, pause game play, then buy as many pandas as needed before resuming the game. After that, wait until the scenario ends.
When a zookeeper cannot access an exhibit because it is blocked, put the zookeeper in the exhibit. He or she will place the food. Then, take him or her out again and put them back on the path.
Alternatively, adopt a herbivore such as a tom gazelle or a sheep family animal into a carnivore's cage. Although red angry faces will rise up from the carnivore's head, it will chase after the herbivore. Wait and the herbivore will disappear.
Pause game play and click on the button on the side that looks like a bulldozer. After that, click on a fence, answer "No" to deleting it, and the fence will turn red until you put the pointer on it, when the pointer looks like a bulldozer.
