How many mascots did the Sydney olympic games have??
---Three
Ollie, Syd and Millie, designed by Matthew Hattan, are three native Australian animals chosen as mascots for the Sydney 2000 Games. They represent earth, air and water. "Olly", a kookaburra, epitomizes the Olympic spirit of generosity and universal generosity (from Olympic); "Syd", a platypus, represents the environment and captures the vigor and energy of Australia and its people (from Sydney); "Millie", an echidna, is a techno-whiz and information guru, with all the facts and figures at her fingertips (from Millennium).
