En cherchant un truc sur ALBW, je suis tombé sur ça :
"n Hyrule's Cucco Run Mini-game there's a secret to those that manage to survie the Endless Mode for 9999.99 seconds. Players will be heralded as the Cuccomaster, and be given a giant Cucco. The Cucco will then stand in front of the pen and give Link infinite hearts. The giant Cucco will even make a cameo in the ending sequence!
Be warned, as Iwata has stated that no one at Nintendo has been able to survive until the end, and only one person has so far recorded evidence of their completion."
Pour ceux qui comprenne pas, ça dit qu'en gros, si on atteint 9999.99 secondes au mini-jeu des cocottes, on "débloque" une cocotte géant qui nous donne infiniment des coeurs et apparaît également dans la fin du jeu
