In Greek myth the three-headed dog, Cerberus, stands guard at the entrance to the underworld. Cerberus’ job is to let you into hell but prevent you from ever leaving, perhaps like the valet at the Hotel California. One head of the dog represents the past, one the present, and the third is the future.

Cerberus is a massive three-headed dog charged with guarding the gates of the Underworld to prevent the dead from escaping. He is a magnificent beast, companion of Hades and Zagreus….

When his wife, Eurydice, died, he went to Hades to get her back. He played his lyre with such grace and skill that it lulled Cerberus to sleep.

Cerberus’ most potent ability is its looks: It has a mane of snakes, three heads, and a tail which was a living serpent. His looks could frighten many mortals and demigods. It is also very large, and ferocious, with sharp teeth that can slice flesh. In some accounts it was said that Cerberus had a poisonous bite.

The correct sequence is “Blue, green, yellow, blue, red, green.” Walk up to Cerberus and left click it once it falls asleep and the whisker is yours.

Go to the underworld and play the tune on your reed pipe in front of Cerberus. He will fall asleep and you can take the whisker from him.

Enter and talk to Hades, who’ll give you Hades’ Crown. Then exit and find Hercules waiting outside. Pull up the touchscreen mirror again and this time tap on the purple part with the trident to get to Poseidon’s temple. Hercules will stamp his foot on a slab of stone, opening up the path to Poseidon’s throne room.

Hercules will follow you after you obtain a mirror from Aphrodite and collect five items for Zeus: a Hydra scale, a rare flower, the Minotaur’s ring, Cerberus’s whisker and Poseidon’s pearl. Travel to Mythology Island. Go left from the starting screen to reach the Tree of Immortality.
