Question: How do you put Cerberus to sleep in mythology island in Poptropica? Answer: It is pretty simple because all you have to do is get the pipe tune from the muse of music (you can find that inside a really musical looking sort of building) you have to get it because it is really important. You go to where Cerberus is then you play the pipe tune that you learned from the muse of music. you get out your pipe and you play it. That is how you get Cerberus to go to sleep in Poptropica
