The golden eggs are placed within the pile of dragon eggs protected by the female nesting dragons during the first task. Ludo Bagman informs the champions that the golden eggs contain the key to the second task of the Tournament; the eggs have hinges which allow them to open to reveal the clue.
When opened underwater, with Harry's head submerged as well, the screeching sound made by the egg is revealed to be a song. A chorus of eerie voices sing to Harry from the open egg:
‘Come seek us where our voices sound, We cannot sing above the ground, And while you’re searching, ponder this: We’ve taken what you’ll sorely miss, An hour long you’ll have to look, And to recover what we took, But past an hour – the prospect’s black Too late, it’s gone, it won’t come back.’
