Achievements - Placid Plastic Duck Simulator

List of achievements updated for So Many Ducks DLC, specifying which DLC is required and providing additional help.Also available in Traditional Chinese

Note About Multiplayer
Considering that other players may have unlocked more ducks than you have, it may be quicker to unlock any remaining achievements by joining a multiplayer room with other players.

The only limitation is that Quacking the Ice and Hippospace Download achievements are not available to unlock this way, considering that Infinity Cool is currently the only available map.

    Annoying parrot (Hidden)
    Listen to all the phrases

Quack the parrot duck and have it make all 12 unique sounds (4 of them learned by default). New sounds unlock every 10 minutes and the progress isn't saved when exiting the game or leaving to main menu. It's sufficient to leave the duck floating for 1:20h, then quacking it a couple of times.

Sounds (some are in Italian, bold: default):
  1. Ah no-no (?)
  2. (Confused grunt) Aaa-ooh?
  3. Bella bah-ts (?)
  4. Bah-goo-vill-yo (?)
  5. Yip-yip (?) pappagallo (parrot) (?)
  6. Auw!
  7. Coo!
  8. Nuh-uh!
  9. (Lower pitch) Nuh-uh!
  10. Nocto (night)
  11. Hey, what's the problem? (?)
  12. Bah-tah para-zero (?)

There is a, presumably, unused property "soundDetectionRadius" of value 15.0 that may indicate that the sounds were meant to be learned by listening to the environment, but proximity to ducks and other sound sources made no difference from testing.
