Zoo Tycoon Cheats

Make an exhibit with a lion, a bengal tiger and a black bear. This will unlock the yellow brick path.

Name one of your exhibits ''Cretaceous Corral''. This will unlock the Triceratops. I should also note that if you name a brand new exhibit using this cheat, it will crash the game. Everyone who's done it with a new exhibit has experienced this, so keep it in mind.
