If you have the Wind Waker, target him and show it to him. The dancing Elvis lookalike is named Tott. What do You do With the Dancing Guy on Windfall Island? See the Windfall Island section of the walkthrough. Make sure you're standing at the left counter and talk to him from there. You have to talk to Zunari the trader on Windfall Island - but not from behind the counter. You can also talk to the King of Red Lions and he may hint you at where your next destination is. If there's something on the list that you haven't done yet, jump to the section and let the walkthrough guide you to your next objective. It goes through the entire quest in order.
