What do I do?
 

I have sunk McGwhatevertys ship and rescued the merperson however when Elaine told me what to do next I was not listening. I think she said something about LeChuck and Guybrush said he preferred him when he wasn't evil. However now I have no clue about what to do, I think I have travelled the whole map and I cannot find what to do anywhere.

Can someone tell me WHAT I have to do and not HOW please.

Thanks

Well, reload and listen this time. It's practically impossible to miss unless weren't paying any attention at all for an extended period of time, in which case, well, why were you doing that? If you can't do that; cast the summoning ball artifact into the ocean with all your might and recite the magic words.
