How do you get the whisker from Cererus on Mythology Island on poptropica?

Go to the temple of Apollo, and get a reed pipe (It's in the back of the temple.). Talk to the muse holding the reed pipe and she will teach you how to play. After you pass, she will give you a song to make Cerberus fall asleep ( dog is in under world temple ).click the nose then take the whisker.
