When and how do i do this cuz i dont see no chicken ever in this game
Right after you go through the leaves maze stealth part, where you have to avoid Pan's brother, you'll ride an elevator up. At the top you have to take out his bird, use Chaos Bombs on it and you'll get the trophy. You HAVE to use Chaos Bombs to take it out though, or you won't get the trophy. Its the only misable trophy in the game.
