Rescuing animals is an integral part of Disco Zoo, and is the way in which players are able to add animals to their zoo. Rescues can take place in a number of habitats, specified by the color of the "START RESCUE" button at the bottom of the Helipad screen (light green for Farm area; light brown for Outback area; yellow for Savannah area; dark green for Northern area; blue for Polar area; somewhere-between-light-and-dark green for Jungle area; and dark brown for Jurassic area). Habitats can be changed by clicking on the "Aircraft Hangar" button.
The way in which players rescue animals is by playing a tile-based mini-game, initiated by clicking the "START RESCUE" button on the Helipad screen, and provided the player has anough coins to perform the rescue. Rescuing animals takes a number of coins based on location. Each time you attempt a rescue, the price for each rescue will increase, until it reaches a maximum price in coins.
