Sirens, Scylla and Charybdis
Odysseus is curious to hear the sirens so he has his men tie him to the mast of the ship. He puts wax in his men's ears so they can't hear the sirens. After they get past the sirens, they notice the waters get rougher and know that Scylla and Charybdis are up ahead. Odysseus doesn't tell his men about Scylla, the 6 headed monster, so they won't try to hide and lead them into the whirlpool. Scylla eats 6 of Odysseus' men, but they row on to the next danger.
Tie me to the mast and put wax in your ears to block the sirens!
Oh no! There's rough waves... that means Scylla and Charybdis is ahead!
Everyone keep rowing!
If I don't tell my men about Scylla, then they wont try to hide which will lead us into the whirlpool! 6 is better than everyone!
