ZT2: There is a never used ambient domestic sheep left in the game files.

There is also 'Forest Floor' terrain, which in the final game was divided into Deciduous and Rainforest terrain.

Salt Water terrain was once intended to be 'Deep Water', and Fresh Water 'Shallow Water'.

The flowers don't need to be watered in the final game.

Miscellaneous unused animations wolves (both Artic and Gray, and both adults and pups) being able to swim, Zookeepers carrying bags, and the maintenance workers watering flowers.

There is also text indicating they intended to add a anthill object.

There is text indicating they planned for the player to be able to purchase premade exhibits of different biomes.

Much like with the prototype tutorial's insult, this losing screen openly says 'YOU LOSE!' in the image. Rather than the zookeeper encountering an animal stampede like in the final game, a group of guests are shown running from a lion pride.

A prototype losing screen also exists.

The game actually calls you a loser(!) if you bother to fail it.

There is a alternate prototype tutorial that is very useless you can complete it just by making the smallest possible exhibit and hiring a zookeeper.

There is a single unused image (possibly from a unused model?) of a mother chimp carrying a baby on her back.

There is also unused text indicating certain animals would complain if there was not enough waterfalls in their exhibit. There is data for this in the prototype, but with no graphics implemented.

The player was originally going to be able to make waterfalls.

The logo in the prototype has a roaring lion head like the MGM lion.

In the prototype, Emperor Penguins and some other animals turn into lions when attacking guests, then turn back to normal.

See it, and also the other stuff mentioned below here. Obviously, it was inappropriate for the rating, so the bloodless version was used instead.

Strangely, there is a alternate version of the dust cloud that appears when animals fight with fully animated blood spraying, and even bones flying left in the game files.
