An integral aspect of Disco Zoo is the mini-game that enables players to "rescue" animals from different geographical locations and add them to their zoo. The mini-game is started by selecting the "START RESCUE!" button on the Helipad screen, and consists of revealing tiles on a 5x5 grid. Hidden tiles can contain parts of animal patterns, currency (in the form of coins or Disco Bux), or nothing at all. If a player reveals a pattern below the tiles, the animal that matches that pattern will be "rescued", and either added to the player's zoo, or released into the wild. Releasing animals incurs a monetary reward, and contributes towards the attainment of statues in the relative Statue Garden, found between the helipad and the Office.
Patterns remain the same for each animal over every mini-game, and increase in complexity for animals with a "rare" or "mythical" status (as well as the level associated with the geographical location each mini-game is played in). Below are the patterns for each animal, based on geographical location:
