These animals appear automatically in water that the player places, but are non-adoptable and cannot be moved (or eaten by inhabitants of tanks). In the following expansion, Extinct Animals, this was changed so the beaver and crocodile could now submerge. Polar bears and emperor penguins from the unexpanded Zoo Tycoon 2 were updated to swim underwater, while Nile crocodiles and American beavers were left as Blue Fang Games believed, contrary to scientific fact, that those two were incapable of doing so. Animals which use land will generally accept either the rock or desert islands instead of normal land, and so may be kept in tanks or hybrid exhibits. Animals like the rockhopper penguin or California sea lion, which live in coastal areas, require a combined land and water exhibit to remain happy. Players are also able to swim with certain animals, by "riding" on them.Īnimals can use either a tank or regular exhibit water. Tricks by different animals in the same act as each other takes place at roughly the same time.Īnimals which can perform in shows must be trained first, either by the player playing minigames, or by hiring a trainer. The player choreographs the show by adding trick into the acts of the show. The shows take place in a tank adjacent to the animal's regular tank, accessible through a tank portal. The difficulty of the training is increased by the form becoming narrower, the tracer moving more quickly and the addition of such obstacles as the player needing to press an arrow key or click the mouse at a certain point. The training increases the animal's skill in that particular trick, as the animal becomes more skilled the training becomes more difficult. The player uses a "training wand" to follow a tracer along a form which differs with the trick that is being taught.

The training minigame takes place in a training area, inside the animal's tank. The player can train individual animals in the first-person, guest mode themselves or hire a trainer to train the animals. Marine Mania introduces shows and an animal training minigame (more minigames were later introduced in Extinct Animals) which were previously not in the other expansions of the game.
