The Bremen Mask is given to Link by Guru-Guru. It originally belonged to a dog who was leader of an animal troupe. Link receives the Bremen Mask after listening to Guru-Guru's confession about how he stole it. However, Link will need to listen to Guru-Guru's confession on the night of the First or Second Day, since he and the rest of the Gorman Troupe will flee from the town afterwards.

The Bremen Mask allows Link to play a marching melody, which makes domestic animals other than cows and horses follow Link, who leads them in a brisk march as he plays his Ocarina. The Bremen Mask can be used in the fight against the Ikana warriors to confuse them and make them march along with Link, rendering them vulnerable. It also makes Cucco chicks grow into adults, which is required to obtain the Bunny Hood.
