Huntin' Du'Cate

Huntin' Du'Cate is a quest in Legend of Mana.

Solution
Talk to Sotherbee to begin the quest. Go Right and return immediately to try to catch the Lilipea. You can't catch it, and this seems to have no point, but you will probably become lost because the Jungle shifts randomly. Eventually you'll encounter a character who casts a "spell" on you, telling you it will prevent you from getting lost.

With this spell cast on you, continue wandering around until you encounter Skippie. Talk to him and agree to help him--if you suggest including Hamson, he will refuse. Once you have Skippie, find Hamson and agree to help him also.

With both Skippie and Hamson in tow, follow them generally rightward and go up when you can't go right. Eventually you'll reach a clearing with the Du'Cate, a giant bear-monkey hybrid thing.

The Du'Cate fight is relatively straightforward as he can be kept stunlocked with most weapons by simply continuously attacking at a moderate pace.

Fight and defeat Du’Cate to get a 500 Lucre reward. Choose to give the money to the others to get the Sand Rose AF.
