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.
