code fish tycoon
1. Once your zoo develops, you will automatically be given a message saying you have unlocked more animals and objects. 2. Click on the research tab, and you can unlock more things for your animals and your zoo. You can unlock: more shelters, animal houses (attractions), endangered animals, staff training, animal care, etc. 3. Purchase expansion packs for Zoo Tycoon and you will unlock different kinds of animals, like marine animals (ex. dolphins) and extinct animals (ex. dinosaurs). The following are cheats to unlock more items. If you know some, please submit. 1. Rename an exhibit "Xanadu" (Xanadu means "magic"). Do it to an already placed exhibit. Many peoples' games have crashed from doing it to a new exhibit. Once you rename the exhibit, you will be able to adopt a unicorn.
There is no unlock code for Roller Coasters in Tycoon 3. To unlock the roller coasters you must go into career mode and complete the scenarios.
I am pretty sure they're 7 mythical creatures they are the... Yeti, Sasquatch, Unicorn, Giant Squid, Lochness Monster, and Evil penguin and the Mermaid. To unlock the Unicorn rename an exhibit Xanadu. To unlock the Evil Penguin, make a penguin exhibit and then put a zebra in the exhibit, the penguin will kill the zebra and it will become faster. To get the mermaid make an empty tank and put a mermaid statue in it.

I'm really not sure, because I've been playing zoo tycoon when I was a kid and I know you can have some pretty cool animals. I don't think so, but you should get a video game PC cheat book and find out. :)
You can download some of them or you can do the objectives and unlock them

You have to have Zoo Tycoon, Marine Mania. The mermaid statue comes as part the game but you have to unlock it. You know... by playing the game and time. It's in one of those "You have just unlocked new animals and items" pop-up thingies. Hope that helps! ~DarkestNyght
