Jilna Fullgood tells you, "Now that King Oolutanga is free of Mudmouth's hold I can treat him for the Jungle Orchid poison Mudmouth gave him. It's amazing he survived really. That much poison would have killed any normal Tusker. To create more of the potion he needs I'll need more King's Crown."
Jilna Fullgood tells you, "You can find the King's Crown water lily at the base of a giant tree overlooking the Chapel of Xi Ru on the last of the Vesayen Islands. Be careful, I hear it is protected by Moarsmen."
Jilna Fullgood tells you, "Oh, if you are able to find and destroy Mudmouth, I have been honored by Oolutanga to reward you in exchange for any befouled treasures he may have wrought."
