Game appearances

Sonic Adventure/Sonic Adventure DX: Director's Cut

The Koala made its debut in Sonic Adventure and Sonic Adventure DX: Director's Cut. In gameplay, Koalas can alter the stats, appearance and personality of a Chao. These animals are found inside Badniks. Simply destroy the Badnik to release the Koala inside, and then touch it to pick it up. When released, the Koalas have a green sphere around them, which disappears shortly afterwards. They are found in the following Action Stages:

Upon entering a Chao Garden with a Koala, it will leave the playable character and run around the garden. The Koala will sparkle if it has not given them to a Chao in the garden. Should the player give a Koala to a Chao, the Chao will embrace it, attaining its appearance and behavior and raising its stats according to the Koala's. The Koala will then lose its sparkle and disappear shortly after.
