Zoo World

A game by the company Rock You played via Face Book, where the player builds and maintains a virtual zoo.

This game contains examples of these tropes:


 * Altitis: As having Zoo Mates is very helpful for obtaining collectibles and other gifts (such as upgrading the rose garden), this is useful.
 * Experience Points: Obtained by feeding animals and collecting hearts.
 * You Fail Biology Forever: Florida panthers, among other animals, are shown to hatch from eggs.
